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 π rad without causing significant amount of intensity modulation.
