concave holographic grating

基本解釋

Design of a dispersing system based on a multi channel detector and a flat field holographic concave grating.
采用平場凹面全息光柵和多通道檢測器設(shè)計了一個小型的色散系統(tǒng)。
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.
基于全息凹面光柵理論和ZEMAX軟件，設(shè)計了一種用于平場光譜儀的消象差平場非球面全息凹面光柵。
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.
與采用相同口徑、相同相對孔徑的全息凹球面光柵構(gòu)成的平場光譜儀比較，在入射狹縫寬度相同的情況下，該光柵所構(gòu)成的平場光譜儀的分辨率得到明顯提高。
