THEORETIC ANALYSIS OF 2-D BEAM STEERING WITH DUAL-EDGE
双光楔两自由度波束导向的理论分析

The effect of dual-edge rotations on beam direction is discussed. The dual-edge physicl mode and the mathematic mode of 2-D precise beam steering are established. From the optical ray refraction theorem, the beam steering formula is deduced. According to this formula, which has been proved by an experiment, the control equation of beam direction is made out and the beam steering speed is analyzed in detail.
