摘要：

In this paper, we present a bistatic scanning imaging lidar optical system. A double-sided scanning mirror is used in this system, which can compensate image spot migration. Geometrical optical analysis is conducted for the scanning light path and an optimal detector position is given. The optical simulation is also implemented using soft-ware Zemax to verify the compensation effect of double-sided reflector. An experiment is carried out with a CW-HeNe laser to observe image spot migration in different positions. The experimental results are in agreement with simulation results. In addition, imaging experiment is performed using 905 nm pulsed laser in the laboratory. The scanning image for black and white stripes target is obtained by single-element detector. Theoretical and experimental results confirm that the use of a double-sided flat reflector can effectively compensate image spot migration. (C) 2013 Elsevier GmbH. All rights reserved.
