This paper proposes a method for the optical system design of uniform scanning in a larger scan field of 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°×40° with small spot size for the target at distance of about 100 m.
本文提出了一种用于三维成像激光雷达中在更大扫描视场（FOV）内进行均匀扫描的光学系统设计方法。推导了该设计方案的理论公式。通过使用光学设计软件ZEMAX，设计了一种基于微机电系统（MEMS）的折叠式均匀扫描光学系统，并对该系统在垂直于光轴的目标平面上的扫描均匀性和光斑尺寸进行了分析和讨论。结果表明，所设计的系统能够在40°×40°的视场内均匀扫描，对于距离约100 m处的目标具有较小的光斑尺寸。
