4.分析通过计算作为滤光片-探测器距离及滤光片带宽的函数的相对信号幅度,对把为本项目研制的元件组合后所预期的性能进行了分析。这种分析是以每个探测器元件所接收到的光学信号为基础的。假定来自光栅的波长为λ_0的单色辐射被聚焦在焦平面的x_0处。在与焦平面相隔D距离的滤光片处,辐射是以一定的时间间隔x_0±x_m照射该滤光片的,利用方 4. Analysis The expected performance of the components developed for this project was analyzed by calculating the relative signal amplitude as a function of filter-detector distance and filter bandwidth. This analysis is based on the optical signals received by each detector element. It is assumed that monochromatic radiation of wavelength λ_0 from the grating is focused at x_0 of the focal plane. At a distance of D from the focal plane at the filter, the radiation is irradiated at a certain time interval x_0 ± x_m with the filter
