Research on Instrument Requirements and Configuration for High Resolution Infrared Observations

High resolution infrared remote sensing can realize all-day, noncontact, high-precision temperature measurement such as the atmosphere, water and other objects, which is an important means of environmental monitoring and resource detection. But High-resolution infrared data are relatively scarce data sources, especially thermal infrared. This paper introduces the research on instrument requirements and configuration for high resolution infrared observations. By using large aperture and integrated optical system combined with linear push broom, high resolution multi-spectral imaging can be realized which covers multiple detection channels from visible light, short wave infrared, mid-wave infrared and long wave infrared spectral bands, and remote sensing data with a panchromatic resolution better than 1 m and an infrared resolution better than 5 m can be obtained, which can serve environmental protection, mineral exploration, and urban remote sensing after ground processing. Through the research in this paper, it provides a reference for the design and engineering of high resolution infrared payload.
