紧凑型空间调制傅里叶变换光谱仪

Compact Spatially Modulated Fourier Transform Spectrometer

提出了一种结构简单的紧凑型空间调制傅里叶变换光谱仪 ,它是基于由两块半五角形棱镜构成的环行共光路干涉分光装置和电荷耦合器件 (CCD) ,具有无机械扫描、全谱同时测量、通光能力强、结构性能稳定和制造成本低等优点。给出了这种光谱仪的分光原理、系统结构及实验结果 。

A simple and compact spatially modulated Fourier transform spectrometer is introduced based on a Sagnac interferometer composed of only two half pentaprisms and a CCD detector.The spectrometer has such advantages as non mechanical scanning,and simultaneous measurement over its whole spectral range,as well as high luminous flux,good stability,and low cost,etc.The principle of spectroscopy,structure,and some experimental results are given.
