Abstract

A method to measure the phase distribution of a light wave by compensating its wavefront distortion with a liquid crystal spatial light phase modulator (LC-SLPM) is improved by utilizing the double path mode of LC-SLPM. The characteristics of the double path LC-SLPM is examined experimentally, and it is verified that this device is effective for adaptive optics use because it is able to modulate the light phase over 2(pi) rad without causing significant amount of intensity modulation.
