摘要
为简化系统结构,将激光发射系统与成像接收光学系统合二为一,设计了一种可变远距离收发共用的折射式光学系统。该系统使用分光镜将1064 nm激光和可见光分离,通过调节成像系统焦面及发射系统前透镜位置,可对300~2000 m 范围内物体进行激光发射及成像接收,结合两种功能于一体,采用发射接收共光路的方式,实现了激光光学系统的小型化与轻量化。根据PW法分别设计了主光路前后组镜头初始结构,并使用Zemax软件对初始结构进行优化分析,大大提升了接收系统的成像质量和发射激光能量集中度。最终设计结果满足设计要求,在300~2000 m物距范围内系统发射光斑大小合理并能清晰成像。
Abstract
In order to simplify the system structure, a variable long-distance transmitter-receiver shared refractive optical system is designed by combining the laser transmitting system with the imaging receiving optical system. The system uses a spectroscope to separate 1064 nm laser and visible light. By adjusting the focal plane of the imaging system and the front lens position of the transmitting system, it can transmit laser to objects in the range of 300~2000 m and receive image. Combining the two functions, the miniaturization and lightweight of laser optical system are realized by means of transmitting and receiving through a common optical path. According to the PW method, the initial structure of the front and rear lenses of the main optical path is designed and optimized using Zemax software, which greatly improves the imaging quality of the receiving system and energy concentration of the emitting laser. The final design result meets the design requirements. In the object distance range from 300 m to 2000 m, the emitted spot size of the system is reasonable and it can be clearly imaged.
