摘　　要：脉冲激光测距设备在各种遥感、测绘、控制与导航以及军事目标探测、识别与跟踪等领域广泛应用,而其中的激光发射与接收系统直接决定了设备的测距能力。瞄准远距离、高精度、人眼安全等现实需求,基于人眼安全1.535μm铒玻璃激光器设计了满足远距离测距要求的激光发射光学系统和接收光学系统。发射光学系统采用非球面以减少镜片数量,经设计优化使激光发散角小于0.4 mard。接收光学系统采用摄远型式,减少球差的同时缩短系统的总长度,耦合效率大于90%。系统设计从理论计算上可实现6.7 km远距离测距,且结构极为紧凑,具有较高的工程应用价值。Pulse laser ranging is widely used in remote sensing,mapping,control and navigation,detection,recognition and tracking of military targets.The transmitting and receiving system directly determines the ranging capability of the equipment.To meet the requirements of long-distance and eye-safe,the transmitting and receiving system are designed based on the 1.535μm Erbium glass laser.The transmitting optical system used aspherical surface to reduce lenses makes the divergence angle less than 0.4 mard.The receiving system adopts the telephoto mode to reduce the spherical aberration and the length of the system and the coupling efficiency is greater than 90%.The theoretical calculation shows that the systems can realize long-distance ranging,and the structure is very compact,which have high engineering application value.
