摘要
从激光探测告警光学系统的视场和光学增益出发,分析了浸没透镜的光学增益和像差特性。针对激光告警设备设计了宽视场有增益光学系统:视场角30°,光学增益可达20倍以上,结构简单,对降低激光辐射源功率、增强探测距离有一定的意义,经分析该方案可行。
The optical gain and aberration characteristics of immersion lens are analyzed based on FOV and optical gain of optical systems used in laser warning device. A wide-FOV optical system with optical gain is designed. It gets optical gain more than 20 with full FOV up to 30 degree. The compact system redounds to reduce the power of laser and enhance the distance detected. Its design is analyzed to be feasible.
