Abstract

The invention puts forward a small-sized uncooled infrared imaging spectrometer and a method therefor. The spectrometer comprises a scanning reflecting mirror, an objective lens group, a slit diaphragm, a collimating objective lens, an interferometer, a relay lens and an imaging assembly that are all orderly mounted along a direction of an optical axis; the spectrometer also comprises an uncooled infrared focal plane detector and an interference spectrum processing module, the uncooled infrared focal plane detector is arranged between the relay lens and the imaging assembly, the interference spectrum processing module receives an interference image signal sent from the imaging assembly, the interference image signal is preprocessed and an interference image is restructured; a spectrum image is output; the interferometer comprises a thin prism and a plane mirror that contact with each other, an upper surface of the thin prism is shaped like a zigzag and is provided with at least two peaks, and each peak is aligned with a slit in the slit diaphragm.

Description

technical field [0001] The invention relates to the technical field of infrared spectrum 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 and other fields, 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 increase the spectroscopic components (interferometers, filter devices or dispersion devices, etc.),...
