摘要
从经典的折射方程出发,建立了双光楔两自由度波束精确导向的物理模型,分析了光楔转动位置对激光波束指向的影响,建立了双光楔波束导向的数学方程,推导了双光楔波束控制方程,并对双光楔导向速度作较详细的分析.
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.
