Abstract

A variable focus liquid crystal lens includes a nematic liquid crystal/monomer mixture having a spatially inhomogenous polymer network structure, and an electrode for applying a substantially uniform voltage to the nematic liquid crystal/monomer mixture. The lens is created within a cell by applying a substantially uniform electric field to the nematic liquid crystal/monomer mixture within the cell, while simultaneously irradiating the nematic liquid crystal/monomer mixture using a laser beam having a shaped intensity distribution, so as to induce formation of a spatially inhomogenous polymer network structure within the cell.

Claims (8)

1. A variable focus liquid crystal lens comprising:
a nematic liquid crystal/monomer mixture having a spatially inhomogenous polymer network structure;
and at least one electrode for applying a substantially uniform voltage to the nematic liquid crystal/monomer mixture.
2. A lens as claimed in claim 1, wherein the spatially inhomogenous polymer network structure is circularly symmetrical.
3. A method of making a variable focus liquid crystal lens, the method comprising a step of:
applying a substantially uniform electric field to a nematic liquid crystal/monomer mixture within a cell; and simultaneously irradiating the nematic liquid crystal/monomer mixture using a laser beam having a shaped intensity distribution so as to induce formation of a spatially inhomogenous polymer network structure within the cell.
4. A method as claimed in claim 3, wherein the uniform electric field has a substantially zero field strength.
5. A method as claimed in claim 4, further comprising a step of providing a surfactant for orientating the nematic liquid crystal.
6. A method as claimed in claim 3, wherein the uniform electric field has a field strength of greater than zero.
7. A method as claimed in claim 3, wherein the shaped intensity distribution is circularly symmetrical.
8. A method as claimed in claim 7, wherein the shaped intensity distribution is a Gausian distribution.
