Paper Abstract

The characteristics of Gaussian beam and the transition function of lens are analyzed in this paper. Based on the principle of liquid crystal optical phased array (LC-OPA) technology, an implementation of controlling the divergence angle of the laser beam is proposed. Through simulation, the transformation graph in which the divergence angle varies with the modulation depth is obtained, and the discretization error is also counted. Experiment have been done to verify the feasibility of this method. This method is convenient and can obtain various value of the angle without changing the structure of the device.
