Paper Abstract

Switchable optical filters have been designed and fabricated for optical image processing applications. In particular, the case of filters producing a Gaussian PSF has been investigated. The filter functions are calculated using methods based on the stationary phase approximation and an iterative Fourier algorithm. The resulting phase functions are realized as continuous surface-relief gratings in photoresist by laser-beam lithography. The optical filters are then made electrically switchable by a liquid crystal layer on top of the grating.
