Abstract

The invention discloses a vacuum temperature control self locking real-time scaling device of thermal infrared high spectral imager. The vacuum temperature control self locking real-time scaling device comprises a vacuum black body assembly, a worm wheel bearing assembly and a motor worm rod assembly. The vacuum temperature control self locking real-time scaling device is arranged in front of a thermal infrared high spectral imager telescope for performing in orbit real-time scaling; the requirements of high-precision imaging quality and accurate object spectrum information are achieved. The device has the advantages that the structure is reasonable, simple and compact; a worm wheel and worm rod mechanism is used; the in orbit rotation self locking can be realized; the engaging distance can be regulated for eliminating the processing and assembling errors; a black body plate realizes precise temperature control in a vacuum sealed environment, so that the scaling is precise.

Description

technical field [0001] The invention relates to a real-time calibration device, in particular to a vacuum temperature-controlled self-locking real-time calibration device for a thermal infrared hyperspectral imager. Background technique [0002] The thermal infrared hyperspectral imager is a device installed on a multi-remote sensing platform such as an aircraft to perform dispersion imaging of object pixels. It works in the thermal infrared spectrum and adopts a dispersion-type spectroscopic method. It uses a planar grating + three-mirror group as a spectroscopic component. The load Except for the front telescope, other parts of the system work in a deep shading environment below 100K, so that the system can obtain more than 180 hyperspectral image information of targets between 8.0 and 12.5 μm. It is a new type of The payload system of thermal infrared hyperspectral imager can be practical. [0003] The thermal infrared spectrum (especially the spectral information) is ex...
