Title The Research of Multispectral Light Filed Camera

 

Abstract

Multispectral imaging is the optical detection technology of next generation, widely used in land and sea remote sensing, medical imaging spectroscopy, investigation of military targets and so on. In this paper, our research is transient multispectral imaging based on the theory of light field imaging. Using the method of aperture segmentation, the system can obtain multispectral image of the target at the same time, which improves the efficiency of the detector. The system consists of the main imaging lens, a microlens array and re-imaging system. By placing filter array in the aperture stop of the main imaging lens, it uses the method of aperture to obtain multispectral information of the target, and then use matlab to program for processing the information from the detector. The program obtains the multispectral image with pixels as the processing unit. By designing and debugging prototype, the system take the four-channel spectrum as the example to verify feasibility and correctness of the system.
