【摘要】：提出了用作近红外高光谱分辨率激光雷达(HSRL)光谱滤波器的视场展宽迈克尔孙干涉仪(FWMI)的设计方法。详细给出了FWMI的设计理论和设计指标的确定过程,通过视场补偿及热补偿设计,使FWMI能在一定温度范围内保证较大的入射视场。给出了针对近红外FWMI的设计结果。性能评估表明,所设计的FWMI可接收的视场角大于2°,并在(20±0.5)℃的温度范围内具有几乎不变的工作性能。最后通过容差分析,保证了该设计结果能满足现有的加工工艺。该设计过程和方法对FWMI的设计加工具有一定的指导意义。
[Abstract]:A design method of field-of-view extended Michelson interferometer (FWMI) used as spectral filter for near-infrared hyperspectral lidar (HSRL) is proposed. The design theory and the determination process of design index of FWMI are given in detail. Through the design of field-of-view compensation and thermal compensation, FWMI can ensure a large incident field of view in a certain temperature range. The design results for near-infrared FWMI are given. The performance evaluation shows that the FWMI can receive field-of-view angle greater than 2 and has almost constant performance in the temperature range of (20 0.5) C. Finally, the tolerance analysis ensures that the design results can meet the existing processing technology. The design process and method of FWMI are designed. It has certain guiding significance in processing.
