摘要
应用平面波角谱理论,分析了采样器对光波场采样和分光的基本原理以及对空间采样频率的选择规则,描述了实际研制的大口径采样器的结构设计,并通过数值方法和高能激光大气传输实验研究了高能激光经采样器前/后的远场光斑分布关系。结果表明:利用光束波前采样器能高保真地实现对高能激光束的分光。
Abstract
Based on the angular spectrum theory, the principle of hole grating for sampling beam and attenuating power of high-energy laser (HEL), and the detailed structure design of a large aperture beam wave-front sampler are described. The numerical calculation and experimental results of far-field optical spot of the transmitted beam produced by the sampler are given. The results show that the beam wave-front sampler can attenuate power of HEL with little errors.
