一、前言为了评价全息凹面光栅的成象质量,我们同时采用了两种方法:一是通过光线追迹,求出它的点列图,在理论上进行分析和评价;二是采用拍照该光栅的谱线,在实际上进行核对和最后评价。在设计全息凹面光栅时,得出不同的仪器结构参数(r_A、r_B、ρ、α、β)和记录参数(r_O、r_D、γ、δ),我们根据它们的点列图,在制造之前,就能判断出那些结果使用效果最佳,还能利用它修正记录参数,选定最佳值。然后在制造时实测谱线,并改正各种参数,使它达到优良的谱线质量。本文参照文献着重讨论点列图。 I. Introduction In order to evaluate the imaging quality of holographic concave grating, we also use two methods: one is through ray tracing, find its point column diagram, in theory, analysis and evaluation; the second is to take pictures of the grating The spectrum, in fact, check and final evaluation. When designing a holographic concave grating, we get different instrument parameters (r_A, r_B, ρ, α, β) and recording parameters (r_O, r_D, γ, δ). According to their point chart, You can determine the results of those who use the best results, but also use it to amend the recording parameters, select the best value. Then measured in the manufacturing line, and correct various parameters, it achieves excellent spectral quality. This article references the literature focuses on point column diagram.
