随着加工技术的不断发展，特殊曲面的光学加工已成为可能，它可以采用由特殊曲面构成的光束整形器来实现任意波面的变换。本文根据能量平衡和光程相等的原理，导出一组非平行入射光束的整形器面形设计公式。根据这组公式，设计了用于准直与均匀半导体激光束的整形器。通过计算机模拟，给出了光束整形结果，并具体分析了整形器厚度和折射率对整形光束性能的影响。 With the continuous development of processing technology, the optical processing of special curved surfaces has become possible. It can use the beam shaper formed by the special curved surface to realize the transformation of arbitrary wave surface. Based on the principle of equal energy balance and optical path, this paper derives a set of shaper face shape design formulas for non-parallel incident beams. According to this set of equations, a shaper is designed for collimating and homogenizing a semiconductor laser beam. By computer simulation, the beam shaping results are given, and the influence of the shaper thickness and refractive index on the shaping beam properties is analyzed in detail.
