摘要

根据透镜的傅里叶变换性质,提出了采用光学傅里叶变换加级联光学成像放大并结合有限口径接收的方法来实现自由空间激光光束远距离传输的实验室模拟。由此原理设计了自由空间激光远距离传输模拟装置,该装置主要由大口径、长焦距的傅里叶变换平行光管和三级成像放大镜所组成,最大等效传输距离达2.4×105 km,可用于星间激光通信终端综合通信性能的评估,在设定的误码率下测量终端可能的通信距离,或者在设定的作用通信距离下检测通信的误码率。

Abstract

According to Fourier transforming properties of lens, a method for simulating long-distance propagation of laser beam in free-space by Fourier-transform, cascade imaging magnification and the wavefront sampling with the limited-aperture was proposed. A long-distance propagation simulator was designed by this principle, which mainly consists of a Fourier-transform lens of big aperture and long focal length and following three optical imaging amplifiers and its maximum equivalent propagation distance reaches 2.4×105 km. It can be used for evaluating the communication performances of the intersatellite laser communication terminals, particularly for measuring the bit error-rate under a constant transmission distance or for testing the equivalent transmission distance under a constant bit error-rate.
