Scanning lidar imaging system using a linear detector array is constituted by both sides into 45° angle of mutual mirror composition. The construction of equivalent optical systems is greatly simplified in the imaging derivation process with intuitive method and analytic geometry. The optical imaging formulas are accurately derived for all the spots of the image. Based on the imaging requirements of the Lunar and Mars exploration technology, numerical simulations and error analysis were performed in the paper. It is shown that the maximum distortion ratio of the central spots pillow-shape distortion image is 3.41% in horizontal direction and the excursion of the edge spots by laser pulse at certain divergence angle is 0.194m, 0.096m in horizontal direction and vertical direction, respectively. The work of this paper can provide the theory basis of the lidar imaging signal processing on-line or off-line used in the deep space exploration projects.
