Ultraviolet, visible and ultraviolet prism chromatic dispersion imaging spectrometer

Abstract

An ultraviolet, visible and ultraviolet prism chromatic dispersion imaging spectrometer relates to the technical field of the space remote sensing imaging spectrum and solves the problems of short working wavebands and small dynamic scope of detectable signal of the current imaging spectrometer. The ultraviolet, visible and ultraviolet prism chromatic dispersion imaging spectrometer comprises a CCD (Charge Coupled Device) detector, an electronic system, a telescoping system and a spectrum imaging system; the telescoping system comprises a aperture diaphragm and a telescope; the spectrum imaging system comprises an entrance slit, a planar turning mirror, a collimating mirror, a collimating mirror, an imaging mirror and a sub-waveband attenuation optical filter. The telescoping system images one band of a target into the entrance slit; the spectrum imaging system disperses the entrance slit and images the entrance slit to the CCD detector; and the electronic system acquires and processes the image on the CCD detector. The ultraviolet, visible and ultraviolet prism chromatic dispersion imaging spectrometer has a compact structure, a small volume and a light weight, can carry out imaging spectrum detection for the target of the signal within a big ultraviolet-visible-ultraviolet scope. The ultraviolet, visible and ultraviolet prism chromatic dispersion imaging spectrometer is applied to the field of spaceflight and aerial remote sensing.

Description

technical field

[0001] The invention relates to the technical field of space remote sensing imaging spectrum, in particular to an ultraviolet, visible and near-infrared prism dispersion imaging spectrometer. Background technique

[0002] Imaging spectrometer is a new type of space optical remote sensing instrument that can obtain spectral information and image information at the same time. It is being used more and more widely in the fields of land and resources survey, ocean and atmospheric remote sensing. However, the working bands of existing imaging spectrometers are mostly concentrated in the visible or near-infrared bands, and the working bands are short, so the types of material components that can be detected are limited to a certain extent. In the visible or near-infrared band, the target radiation signal strength has little change, which is 10 3 The order of magnitude is within the dynamic range of the CCD detector itself, so visible or near-infrared imaging spect...
