Abstract

A new technique is proposed to perform several image-processing operations with the same optical system. Each operation can easily be selected by properly loading a birefringent photoelastic plate, which acts as the spatial filter of the system. Thus different pupil transmittance configurations can be achieved, each of which is associated with a certain image transformation.
