Title: OPTO-MECHANICAL DEVICE
Abstract:
An opto-mechanical device comprises an optically responsive actuating member in which a mechanical strain occurs in response to changes in its illumination. The actuating member is preferably at least partly formed from a semiconducting glassy matrix such as a chalcogenide glass. Preferably the opto-mechanical device includes means to illuminate the actuating member with light which is preferably plane polarised. Preferably it also includes means to vary the polarisation angle of the plane polarised light to cause a change in the strain generated in the actuating member.
