人眼安全的激光雷达系统的返回信号频率从红外上转换到可见光通过和频产生的周期性极化铌酸锂纳入接收器。定量分析的角度接受和量子效率，然后提出了一个单一的宏观接收光学和多孔微透镜阵列。比较这两个结果，在宏观系统上，微透镜设计实现了接收器视场的6倍增加和光束耦合的18%增加。
The return signal frequency of an eye-safe ladar system is upconverted from the infrared to the visible through sum-frequency generation by incorporation of periodically poled LiNbO3 into the receiver. A quantitative analysis of the angular acceptance and the quantum efficiency is then presented for a single macroscopic receiver optic and a multiaperture microlens array. Comparing both results, a 6x increase in the receiver field of regard and an 18% increase in beam coupling were realized for the microlens design over the macroscopic system.
