Abstract

Infrared detection technology is getting more and more attention, with the rapid development of infrared remote sensing application. Among them, low temperature infrared spectroscopy detection technology is an important development direction in the future. Infrared detection technology is a kind of target detection technology, using the infrared radiation characteristics of substances to different wavelengths. Infrared spectrometer is an important instrument to realize infrared detection technology. This type of spectrometer has been popularized and applied. The imaging spectrometer can reflect the spatial information and spectral characteristics of the observation target. With the improvement of spectral imaging resolution, the signal-to-noise ratio of imaging system is required to increase, which is the technical difficulty of low-temperature infrared spectroscopy. At present, noise reduction through low temperature is the main method. Therefore, infrared detection technology to work in a lower temperature direction. Furthermore, it promotes the progress of low temperature infrared spectroscopy technology. This paper summarizes and compares the development status of low temperature infrared spectrum detection technology. Thus, the key technology of low temperature detection spectrum is extracted. The low temperature infrared detection technology is classified according to the development status of low temperature infrared optics, low temperature support technology and low temperature refrigeration technology. Summarize the shortcomings of domestic existing technology and look forward to the future development direction.
