为满足动态目标实时光谱成像的应用需求, 设计了一种基于CDP(crossed dispersion prism)的静态、 快照式的光谱成像仪。 对其光谱成像原理进行了理论研究, 并根据理论研究结果对宽波段CDP光谱成像仪光学系统进行设计。 该光谱成像仪由CDP分光系统、 成像光学系统和面阵探测器组成, 视场角为4°, 焦距为110 mm, 工作波段为0.6~5.0 μm。 设计结果表明, 该仪器在0.6~5.0 μm的波段范围内具有较好的光谱成像能力, 平均光谱分辨率为20 nm。 该技术为实时获取动态目标光谱信息及位置信息提供了一种新方法, 同时该技术在对未知高能目标探测、 定位以及识别方面具有很大的潜力。

In order to satisfy the application requirements of real-time spectral imaging for moving targets, we design a static, snapshot imaging spectrometer based on a CDP(crossed dispersion prism). The spectral imaging principle is studied, and an optical system of broadband spectral imaging spectrometer is designed according to this principle. Imaging spectrometer consists of a CDP, an imaging lens and a detector, with ±2°field of view, spectral coverage from 0.6 to 5.0 μm, The results show that this instrument has a better ability to detect spectral from 0.6 to 5.0 μm while the average spectral resolution is 20 nm. The technology for dynamic target real-time spectral imaging provides a new technical way. It has a great potential for detecting, locating and identifying unknown energetic events in real-time.
