OPTICAL DEVICE

摘要

The following invention relates to an optical device for use in a system that requires optical zoom or focus abilities, particularly for providing pre-set zoom parameters with a very low energy requirement. There is provided an optical magnification device comprising at least one pair of optically aligned deformable reflectors, wherein each reflector pair has at least two configurations, wherein selection of a first and a second configuration of said deformable reflector pairs provides pre-defined magnification states, such that in any configuration one reflector is substantially concave and the other is substantially convex; at least one controller may cause both the reflectors to move between said at least two configurations.

1. An optical magnification device comprising:
at least one pair of optically aligned deformable reflectors; and a controller for said deformable reflectors; wherein each reflector pair has at least two configurations, wherein selection of a first and a second configuration of said one or more deformable reflector pairs provides pre-defined magnification states, such that in any configuration one reflector is substantially concave and the other is substantially convex, wherein said each deformable reflector pair comprises a first deformable reflector and a second deformable reflector, wherein the first deformable reflector is optically aligned with the second deformable reflector wherein the pair of reflectors are operably linked, such that causing the first reflector to deform from a first state to a second state causes the concomitant deforming of the second reflector from its first to second state, and wherein the deformable reflectors are bistable reflectors.
