Abstract

Limited by the current technological development level of infrared detectors, it is difficult for the infrared multispectral imaging systems to meet the requirements of practical engineering application indicators such as low structural complexity and high transmittance at the same time. In order to promote the engineering application level of computational imaging technology in the infrared spectrum, this paper proposes a snapshot computational spectral imaging technology scheme based on reflective coding mask; this scheme utilizes the built-in reflective coding mask in traditional imaging system: Firstly, complete the design and molding of the coding mask according to the index requirements, complete the information calibration of the coding mask in the spatial dimension and the spectral dimension by building a high-precision spectral calibration module, and then combine the compressive sensing image restoration algorithm according to the calibration results, finally realize the Imaging and spectral data extraction of targets. Laboratory indoor imaging shows that this scheme can realize broad-spectrum imaging of indoor targets and extraction of multi-spectral information of targets. Compared with the technical scheme of traditional optical filter and grating infrared spectrometer, it has the technical advantages of simple structure and high transmittance.
