concave holographic grating

基本解释

Design of a dispersing system based on a multi channel detector and a flat field holographic concave grating.
采用平场凹面全息光栅和多通道检测器设计了一个小型的色散系统。
Based on the holographic concave grating theory and ZEMAX software, an aberration-corrected flat-field holographic concave grating on aspherical surface for a flat-field spectrograph is designed.
基于全息凹面光栅理论和ZEMAX软件，设计了一种用于平场光谱仪的消象差平场非球面全息凹面光栅。
Comparing this spectrograph to the one with a holographic concave grating on spherical surface, the former has a higher resolution than the latter has when the widths of the incident slits are same.
与采用相同口径、相同相对孔径的全息凹球面光栅构成的平场光谱仪比较，在入射狭缝宽度相同的情况下，该光栅所构成的平场光谱仪的分辨率得到明显提高。
