Paper Abstract

In order to improve the image reconstruction quality of multispectral correlation imaging system under the condition of low illumination, this paper proposes a multispectral correlation imaging scheme based on laser active illumination. In this scheme, the phase modulated multispectral correlation imaging camera is used as the experimental platform, and the laser is used as the auxiliary light source to increase the reflected signal intensity of the target object, and the image information of the target object is obtained through single exposure. The experimental results show that compared with the reconstruction results of multispectral association imaging under the condition of low illumination, the active and passive combination scheme can significantly improve the image reconstruction quality of the multispectral association imaging system. This paper is of great significance to promote the practical application of new multispectral imaging technology.
