Abstract

A liquid crystal programmable phase modulator (PPM) was evaluated acting as the active element on an adaptive optics system. This device (Hamamatsu X7550) consists of an optically-addressed liquid crystal spatial light modulator coupled to an intensity light modulator through an optical system that removes pixelation. Therefore, it is theoretically free from the diffraction patterns produced by the pixel structure in the electrically-addressed liquid crystal devices.
