Embodiment
Shown in Figure 1 is that a notion photoswitch 1 has 24 input ports 2 and output port 3.
In this embodiment, port comprises rod-shaped lens collimating apparatus 4, and this collimating apparatus and corresponding optical fiber connect together.In use, input port and output port are fixed.In fact, when mounted, in order to obtain passing through accurately the optical communication passage of switch, each port all is can be controlled.Each output port 3 all has the fixing latent prestige prism of a correspondence, is respectively prism 5,6,7 and 8 (can only see that in the drawings prism 8 bottom).On the latent prestige prism as prism 6 two inclined-planes 9 and 10 are arranged, these two inclined-planes are used for reflection ray, to change the direction of propagation of light.Dive and hope that prism can elongate, their length is several times of width.In the present embodiment, Gu Ding prism approximately is half length of mobile prism 11,12,13,14,15 grades of correspondence.Mobile prism 11 links together by a suspension arm 17 and stepper motor 16, and the extension of suspension arm 17 is vertical with the rotating shaft of stepper motor 16, and the tie point of suspension arm 17 and prism roughly is positioned at the mid point of prism.The radius of prism 11 so just can be selected input port arbitrarily corresponding to the radius of input port arc.
Placements that overlap mutually of the fixed prism of the low side of mobile prism and its correspondence forms optical channel, and light beam enters fixed prism through mobile prism, arrives output then.The radius of selecting fixed prism is with the radius corresponding to the output port arc, but the radius of the radius of fixed prism and mobile prism is different, to obtain better structural compactness.
Connect for all obtainable light, this combination can access a fixing article entire length.Dive and hope that prism also has an advantage, Yan Ge system perspective tolerance is within the margin tolerance of the direct commercial prism of making exactly.Bigger advantage is, the optical characteristics of prism and prism radially and axial location irrelevant.Unique requirement is that the turning axle of prism needs with one heart, and this is the error requirements of a strictness, but can adopt the existing commercial Positioning Gear head of using to satisfy tolerance.
A feasible drive motor may need the speed in 20 step/weeks, by the seamless gearhead of the high precision of a 120:1, obtains 0.15 ° step pitch under situation about advancing without micro-stepping.At radius is the end of the arm prism of 12mm, and 0.15 ° stepping is equivalent to the stepping distance of 30 μ m, and like this, system just can have good resolution and acceptable motor is lost the step.
Input port in the present embodiment can be on the arc of a radius 12mm integrated 24 collimating apparatuss of 2mm at interval.Prism is of a size of 1*1*13mm
3, two end faces are 45 ° inclined-planes, like this, the light path of a 12mm are just arranged in prism.Adopt hall effect sensor and small magnet to detect, by detect prism and magnet by the time opposite flux, just can determine stepping zero point.The present invention has also considered other potential feasible switches.Such as, a switch has an input port arc and an output port arc, a plurality of collimating apparatus that input arc and output arc are all integrated, and input arc and output arc can be supported a lot of collimating apparatus ports.Input port and output port all are designed to only need in use to install once.Between input port and output port, two kinds of different mobile switching devices are arranged.A kind of mobile switching device is by comprising an electric rotating machine, the axle of this electric rotating machine can drive with different angle orientation precision, this axle can link together by a dish and mobile prism, and the groove that also can hold mobile prism according to the size of mobile prism is arranged on this dish.Upwards, the end that is connected the cantilever on the plate has a magnet in the footpath opposite with prism.A magnet can constitute the part of a hall effect sensor, and this hall effect sensor is positioned at the bottom of the supporting rod of a rotor.In order to reduce the set-up time and to improve degree of accuracy, each rotating prism axle comprises a code device based on inductance coding or capacitive encoder printed circuit board (PCB) and so on, rather than the hall effect sensor combination.
Rotating prism forwards light beam on the collimating apparatus fixed prism.Only by adopting a mobile prism combination just can set up optical channel between the central collimator of collimating apparatus and corresponding array of ports.Central collimator in the present embodiment does not show on figure, but its turning axle along prism is accurately located.
Suitable situation, servomotor is applied the stepper motor shown in the replacement figure.In order to keep enough rotation amounts that passes switch, the consideration service efficiency is lower than 50% gearhead or increases a friction plate or add the lock of a driver control at output terminal at output terminal.Faster speed can adopt direct motor-driven (such as there not being gearhead, prism directly is connected on the axle) if desired.Also can consider to adopt the piezoelectricity disc type electric machine, this piezoelectricity disc type electric machine can form a very compact driver or, as alternative scheme, the wheel that can adopt piezoelectricity-inch (piezo-inch) worm screw array to drive to be used for fixing prism or the edge of disk.
Each collimating apparatus all is fixed in the annulus, and the front end of collimating apparatus is fixed in first bent plate, and the rear end of collimating apparatus is fixed in the bent plate.Collimating apparatus will fix by the hole of opening on the appropriate location on the bool.Bool is clamped between a center ring and transportable ring of front end, and bent plate is clamped between a center ring and the afterbody ring.These rings are joined together by thread mechanism or other suitable structures.On the outermost top of bent plate, except two additional eyelets, also have a pattern (cut-out) in each bent plate, this pattern can be used to adjust collimating apparatus is passed through switch with acquisition with respect to the position between its supporting construction best optical channel.
Another alternative switch comprises an input array that links to each other with output array.The all corresponding fixed prism that is connected with the latent prestige of rotation prismatic light of each collimating apparatus of an array, this rotation is dived and is hoped that prism has a selectable radius, imports the light beam of collimating apparatus ejaculation with any one of catching from another array.When dive hoping prism around the switch shaft rotation, the grooved prism just can be caught the light beam that comes out from collimating apparatus arc or prism arc.Single transportable latent prestige prism discs can drive with the motor that is installed in the disk side by gear structure, to obtain maximum system compact.
Can make improved optical switch, this optical switch has about 24 input ports and 5 output ports to be operatively connected.The integrated rod-shaped lens collimating apparatus that is connected with optical fiber of port, this optical fiber supports on the annular support member by two bools.Each collimating apparatus all is supported on the supporting construction of its correspondence.Each outlet all dive to hope prism have optics to be connected with one, dive and hope prism be fixed the location catching from the next light beam of switch central shaft, and with these beam reflection to output port.Each fixed prism moves with getting around the mobile prism that closes the central shaft rotation, to catch the light that penetrates from any input port.
Dive and hope that prism can link together with rotating circular disk.Outermost at rotating circular disk is with a lot of apertures, can allow light pass through in position.Disk driving wheel and disk engagement, the disk driving wheel leans on the direct-connected turbine drive of spin motor shaft with stepper motor and so on.Driving wheel, turbine and electric rotating machine concerted action.Switch can integrated five displacement mechanisms, and these displacement mechanisms link together by a series of longitudinal beam.Each ring all comprises a lot of projection eyelets, passes through to allow suitable light.
These switches can adopt modular manner manufacturing.Switch can integrated 20 medium drives rather than foregoing 5 drivers make up.The all integrated fixed disc of each driver, this disk and prism link together, and are used to catch the light that comes out from port, and guiding light leads to the center switch axle.Each driver is also integrated removable disk has second movably prism on this disk, can guide light to lead to a port.Driver that each single actuator unit is all adjacent with it or terminal supporting construction link together, and form an interlocked relationship, just as the projection of end support unit and the projection of actuator unit mesh together.
This switch designs is for having 96 port *, 20 ports.
Figure 2 shows that a selectable driving prism is to combination.In this framework, two related drivings of prism.As long as axle 88 rotates, prism 86 and prism 87 will rotate together.Second prism is to being respectively prism 89 and prism 90, and they link together by optical link thing 91.This system allows the deflection of light, and is such with regard to dot-and-dash line shown in the image pattern 92 and dot-and-dash line 93.
Collimating apparatus and so on optical device that is similar in switch and the filter plate requires accurate location, so that light effectively is coupled.Fig. 3 has showed two 2 dimension piezoelectric actuators of parallel placement, the application of piezoelectric beams 94 and piezoelectric beams 95.These actuator beam support to suitable support structure 96 and supporting construction 97 arbitrarily at their least significant end.Piezoelectric beams 98 is connected extension rod 100 and 101 respectively with 99 foremost theirs.Extension rod 101 links together with collimating apparatus 102 by the fixture 103 of its bool that includes two known kinds.In a feasible embodiment, each 2D piezoelectric beams is 31mm in length, and the displacement of one+/-125 μ m is arranged on the directions X at tip and Y direction.Design extension bar 100 drives the displacement of optical fiber with acquisition+/-375 μ m.Extension rod 101 long 46mm are suitable for driving the collimating apparatus end with the displacement at tip location acquisition+/-500 μ m.For instance, such framework can obtain+/-displacement and collimating apparatus optical fiber connector of 0.2mm around+/-radial skew of 0.3mm/10mm.At light path is 130mm, have in the 100mm path on passive collimator arrangement (2mrad, 0.12 °)+situation of the bearing accuracy of/-200 μ m under, can obtain at directions X and Y direction+/-covering of 4mm.This is very suitable for 1*16 switch shown in Figure 4.
Position and angle sensor can be finished by one group of 8 electrode on 104 such sensor boards shown in the image pattern, the separation signal excitation that they are sent by signal generator.Electrode on four electrodes around the hole that the collimating apparatus tip is passed through and other four flat sites that are positioned at the sensor board of placing with metal plate sensor ring opposite is coupled on the collimating apparatus, like this can amplification sensor output.The present invention also considers to adopt the two-dimensional piezoelectric driver of two group shown in Fig. 3, as instrument adjust before the present invention or those switches of using in the position of collimating apparatus.A pair of like this two-dimensional piezoelectric driver can continue the position of tuning each input and output ring fixed port fully.
