摘要：
This paper proposes a method for the optical system design of uniform scanning in a larger scan field view (FOV) in 3D imaging lidar. The theoretical formulas are derived for the design scheme. By employing the optical design software ZEMAX, a foldaway uniform scanning optical system based on MEMS has been designed, and the scanning uniformity and spot size of the system on the target plane, perpendicular to optical axis, are analyzed and discussed. Results show that the designed system can scan uniformly within the FOV of 40 degrees x 40 degrees with small spot size for the target at distance of about 100 m. (C) 2015 Optical Society of America
