A spectral detection system

Abstract

The invention provides a spectrum detection system, comprising a multi-angle dual-band telescope group, an optical fiber image transmission bundle and a high-resolution spectrometer, the multi-angle dual-band telescope group images multi-angle dual-band radiation on the image plane, The first end of the fiber optic image transmission bundle is located on the focal plane of the multi-angle dual-band telescope group, and the second end of the fiber optic image transmission bundle corresponds to the incident slit of the high-resolution spectrometer. The imaging is transmitted to the incident slit of the high-resolution spectrometer, and the high-resolution spectrometer divides the imaging on the image plane into dual-band images on the same detector image plane; wherein, the multi-angle dual-band telescope group includes at least two different angles A first waveband telescope and at least two second waveband telescopes with different angles. The spectrum detection system provided by the invention can meet the requirements of multi-angle and dual-band, improves the information acquisition ability of the instrument, and reduces the volume and weight of the instrument.

Description

technical field [0001] The invention relates to the technical field of atmospheric spectral radiation detection, in particular to a spectral detection system. Background technique [0002] In the field of atmospheric spectral radiation detection, aerosols, water vapor, and clouds are the three main parameters that affect global changes and atmospheric energy cycles. Through the long-term accumulation of data on the spatial and temporal distribution of the three parameters, we can better understand, predict and evaluate them. The impact of activities on global change, and how human beings can change their lives and production methods to better adapt to and regulate the trend of climate change. Spectral detection of aerosols, water vapor, and clouds is an important detection method, that is, through the physical relationship between high-resolution radiation spectra and atmospheric aerosols, water vapor, and clouds, an inversion method from spectral measurements to atmospheric...

Problems solved by technology

However, the existing atmospheric spectral detection system can only perform simultaneous spectral detection of radiation in a single angle and a single band, which cannot meet the needs of multi-angle, dual-band simultaneous detection of aerosols, water vapor, clouds, etc.
