英文摘要： As an emerging technology, active 3D multispectral imaging has broad application prospects in the military field and civilian areas.3D spatial information and spectral radiance information can be obtained at the same time through this technology. It combines the 3D imaging technology and spectral measurement technology. We can improve the accuracy of target detection and extend the functionality of the traditional detection technology through active 3D multispectral imaging. It is a qualitative leap in the photoelectric detection technology. Wavelength Conversion technology which transform the different wavelengths of laser to the peak wavelength of the detector response is proposed in this project. Active 3D multispectral imaging is implemented through streak tube detector which is responded in visible light only.This technokogy can improve the 3D multispectral imaging frame rate obviously and reduce the difficulty of data fusion.The basic research of the active 3D multispectral imaging carried on in this project.
