Abstract

An experimental demonstration of nonmechanical optical image rotation to 20 different angles is described. The optical system consists of a polygon mirror with 20 facets in a half cylinder and a 2-D acousto-optic beam deflector. Experimental details including the requirements of components are described. Various issues such as number of rotation angles, resolution, aberration, and noise are analyzed.
