摘要：
Beam steering characteristics of transmission liquid crystal optical phased array (LC-OPA) were measured using ultra precision electronic autocollimator. A continuous beam steering with a constant angular resolution in the order of 20 mu rad is obtained experimentally from 0 degrees to 6 degrees based on the method of variable period grating (VPG). Meanwhile, the angular repeatability of less than 4 mu rad (RMS) has been achieved.
