Abstract

The present invention proposes a miniaturized uncooled infrared imaging spectrometer and method, wherein the spectrometer includes sequentially installed along the optical axis direction: scanning mirror, objective lens group, slit diaphragm, collimating objective lens group, interferometer, relay mirror and an imaging component, the spectrometer also includes an uncooled infrared focal plane detector and an interference spectrum processing module, the uncooled infrared focal plane detector is placed between the relay mirror and the imaging component, and the interference spectrum processing module receives the interference image sent by the imaging component signal, preprocessing the interference image signal and reconstructing the interference image, and outputting the spectral image; the interferometer includes a thin prism and a plane mirror in contact with each other, wherein the upper surface of the thin prism is jagged, with at least two peaks, each The spike is aligned with a slit in the slit diaphragm.

Description

technical field [0001] The invention relates to the technical field of infrared spectral imaging, in particular to a miniaturized uncooled infrared imaging spectrometer and a method. Background technique [0002] Infrared imaging spectrometer can provide scene image information and spectral information at the same time, so as to deeply analyze the composition and characteristics of scene targets. It is an important observation, analysis and detection equipment. At present, infrared imaging spectrometers have been widely used in stealth target reconnaissance, dangerous gas detection, environmental pollution monitoring, resource exploration, maritime search and rescue, etc., and are gradually becoming an important market growth point in the field of photoelectric imaging. [0003] Compared with ordinary infrared thermal imaging cameras, infrared imaging spectrometers add spectroscopic components (interferometers, optical filter devices or dispersion devices, etc.), which also ...
