Problems solved by technology

[0005] Judging from the infrared imaging spectrometers under research and successfully developed, most of them use the classic Michelson mechanism, using plane mirrors or corner mirrors to split light; most of the driving devices of the moving mirrors use porch-swing, using voice coil motors or torque motors Drive, this type of device has no mechanical deceleration mechanism, and the load capacity and speed range are limited

Abstract

The invention discloses an infrared imaging spectrometer. The infrared imaging spectrometer comprises a moving mirror driving apparatus, a laser interference calibration system and a moving mirror control circuit. The moving mirror driving apparatus comprises a support base, a stepping motor, a ball screw, an intersection roller guide rail and a slide block, wherein the slide block is provided with a moving stereo pyramid prism. The laser interference calibration system comprises a laser, a reflective mirror, a beam splitter mirror, a compensation mirror, a one-eighth wave plate, a right-angle reflector, a fixed solid angle mirror, a polarization beam splitting prism, a laser detector and a half-wave plate. The moving mirror control circuit comprises a controller, a detection circuit acting on orthogonal interference signals and a driving circuit connected with the stepping motor. According to the invention, the system load capacity is high, a large-volume solid angle mirror can be driven to perform heavy-load motion, and different requirements of different spectrum resolutions and different application environments for a moving mirror control speed can be satisfied.

Description

technical field [0001] The invention belongs to the field of infrared imaging spectrometers, and relates to an infrared imaging spectrometer. Background technique [0002] Infrared imaging spectrometer is a new generation optical instrument developed in the early 1980s that integrates infrared imaging and spectral information detection. It can provide two-dimensional spatial information and high-resolution spectral information at the same time. It is used in the fields of environmental monitoring, gas analysis, and target radiation characteristics research Wide range of applications. [0003] The specific working principle of the infrared imaging spectrometer is: in a high-precision Michelson interference optical path, a series of interferograms with different optical path differences are obtained through moving mirror scanning technology, and the corresponding spectral diagrams are obtained through Fourier transform. [0004] High-precision moving mirror control technology...
