Abstract

The invention relates to a spectral imaging system, in particular to a spectral imaging system based on forearm compensation and a plane grating, so as to solve the problems of poor imaging quality, complex optical path and difficult processing and adjustment of the existing Dyson concave grating spectrometer. The technical scheme adopted in the present invention is: a spectral imaging system based on forearm compensation and plane grating, comprising a slit, a forearm compensation lens group, a folding mirror, an optical path multiplexing lens group and a plane grating sequentially arranged along the optical axis of the system; The forearm compensation lens group, the optical circuit multiplexing lens group and the plane grating are all arranged on the same optical axis, the slit is arranged on one side of the optical axis of the system, and the folding mirror is arranged on the other side of the optical axis of the system, so A detector is also provided on the side of the folding mirror away from the optical axis of the system.

Description

technical field [0001] The invention relates to a spectral imaging system, in particular to a spectral imaging system based on forearm compensation and a plane grating. Background technique [0002] The spectral imager is a new type of remote sensing instrument that "integrates spectrum and image". It has the characteristics of high spectral resolution, large number of spectral bands, and continuous output in the working band range. It organically combines the traditional two-dimensional imaging remote sensing technology and spectral technology. While using the imaging system to obtain the spatial information of the scene, the spectrometer system decomposes the spectral radiation of the scene into many adjacent or even overlapping narrow areas. Radiation in spectral bands can obtain dozens or even hundreds of narrow continuous band information of each scene pixel within a certain spectral range. In this way, not only ground scene images with multiple narrow spectral bands ...
