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.
