abstract = "Active multi-spectral detection technology is used to acquire the information of the targets{\"i}1/4such as spectrum, distance, intensity, and location and so on. So the active multi-spectral detection technology becomes one of the main trends of development of detection system in the future. Based on the analyzing the theory of streak tube lidar active multi-spectral detection system, we design a wavelength conversion circuit which can be applied to implement wavelength conversion in the streak tube lidar in the active multi-spectral detection. Through the O-E-O conversion mode, the wavelength of laser echo signal which contains the target information is transformed into another wavelength which represents the spectral peak response wavelength of the stripe tube photocathode. The simulation results show that when the input laser echo signal wavelength is 1.55um, and the after-converted wavelength is 0.85um, the photon conversion efficiency can reach 2.2×106,the signal to noise ratio can reach 19.3dB. And when the target distance or the signal bandwidth increases, the signal to noise ratio(SNR) will decrease accordingly.",
