摘要
原子共振滤波器(ARF)是一种超窄带宽(Q～10~5—10~6)、大角度接收、各向同性的光学滤波器,这个特性来源于原子蒸气中的吸收、发射和能量转换过程,它特別适用于消除连续背景噪声的弱信号接收检测系统。本文简述被动式和主动式ARF以及原子蒸气滤波器(Atomic Vapor Filter-AVF)的工作特点及其在水下通信、红外检测和激光(气象)雷达中的应用。并介绍了几个AVF典型例子。
The atomic resonance filter (ARF) is an ultra-narrow-band (Q-10~5～10~6), large-acceptance-angle, isotropic optical filter. The filter properties arise from the physical processes of absorption, emission, and internal energy conversion in atomic vapors. These features make the device specially suited for applications in which weak laser signals are detected against a continuum background. In this paper, we describe the characteristics of the passive, active ARF, AVF and their applications for underwater communications, laser MR and IR quantum detections. Furthermore, representative examples of passive, active and atomic vapor filter (AVF) are presented.
