Abstract

The invention provides a full-field spectral calibration device of a push-broom type imaging spectrometer. The device comprises a light source system (1), a monochromator (2), a collimation system (3) and a field scanning system (4), wherein light emitted by the light source system (1) is converted into monochromatic light through the monochromator (2), changed into parallel light through the collimation system (3) and revived by a to-be-calibrated imaging spectrometer after bent into different angles through the field scanning system (4). According to the full-field spectral calibration device, the parallel light with different field angles can be provided for the to-be-calibrated imaging spectrometer, so that full-field spectral calibration requirements of the push-broom type imaging spectrometer can be met. The full-field spectral calibration device is particularly suitable for full-field spectral calibration of a dispersion type imaging spectrometer in a visible light and infrared band.

Description

technical field [0001] The invention relates to the technical field of spectral calibration, in particular to a full-field spectral calibration device for a push-broom imaging spectrometer, which is particularly suitable for full-field spectral calibration of a dispersion-type imaging spectrometer in visible light and infrared bands. Background technique [0002] Imaging spectrometers can obtain spatial image information and spectral curve information of detected objects at the same time, and have important applications in chemical industry, metallurgy, military, scientific research, astronomy and other fields. From the current situation of aerospace imaging spectrometers at home and abroad, push-broom dispersion The imaging spectrum of the spectroscopic imaging spectrometer is in a relatively dominant position. During the application process, the performance of the imaging spectrometer will be affected by many external influences such as weather and environment, resulting in...
