摘要

设计并实现了一种利用激光束在大气或真空中传输数据的数字话音通信系统。采用市售的650nm红色激光笔和光信号接收器分别作为光源和PIN光电二极管。光无线通信系统由于其固有的宽带带宽、可行性和不需要许可证的特点，在提供宽带服务方面具有很大的吸引力。因此，在室内使用和其他可视通信可行的应用中，光学无线通信提供了无线电频率通信的非正统替代品。数字语音通信系统的设计具有更好的性能和抗噪性。它还提出了安全的数据传输。该基于单片机的单工光无线语音通信系统已经过测试，运行良好。

Designing a Secure, Reliable and Simplex Optical Wireless Voice Communication System

A Digital Voice Communication system has been designed and practically implemented which utilizes laser beams for data transmission through the atmosphere or vacuum. Commercially available 650nm red laser pointers and PIN photodiodes have been used as the light source and the optical signal receiver respectively. Owing to their innate wide bandwidth, feasibility and no license requirement, optical wireless communication systems are alluring for providing broadband services.So optical wireless communication renders an unorthodox substitute for radio frequency communication in indoor use and other applications where line of sight communication is viable. The digital voice communication system has been designed for better performance and noise immunity. It also propounds secure data transmission. This micro-controller based simplex optical wireless voice communication system has been tested and found to be successfully working.
