Abstract

The fabrication and characterization of an optically addressable deformable mirror spatial light modulator is described. Device operation utilizes an electrostatically driven pixellated aluminized polymeric membrane mirror supported above an optically controlled photoconductive GaAs substrate. Interferometrically measured deformation data as a function of illumination, applied voltage and frequency is presented.
