Based on the principle and structure of Streak Tube Image Lidar(STIL), miniaturization and efficient transmission of input and output optical system for the streak tube detector were designed. Considering the Characteristics of the lidar, the peak response wavelength of streak tube was optimized. The electro-optical and deflection systems were designed for high-resolution, and the typical test values of performance parameters of streak tube were provided. Electronic control system comprised of gating supply, sweeping supply, and high precision synchronous control circuit was developed, and the typical test values were provided. It was shown for the whole size of streak tube detector, performance parameters and electrical interface. The outdoor lidar experiment was carried out on the detector, through which clear grayscale images and 3 D images were obtained to prove the feasibility and wide application prospect of STIL.
