Development of laser transmission system using audio signal light reflection modulation technology

本篇文章通过研究音频信号的光反射调制的激光传输系统,为了研究要采用了激光反射系统和接受系统分立设计的思想。通过研究发现能够加大系统的便利性和实用性,还能给检测到的音频信号进行加强,还增加了音频信号的清晰度。现在常用的激光测振的技术有很多,包括:激光多普勒参考光测振技术、全息干涉法等。

Audio signals play a very important role in the process of information transmission,because its importance has also received much attention. One common method of detecting audio signals now is microphone detection and laser detection. When the microphone detection needs to be detected,the distance between the audio signal and the microphone should be kept close,and there should be nothing between the two,or the detection error will occur. Laser detection can detect objects that are relatively farther away.There are many techniques for laser vibration measurement,including laser Doppler reference light measurement technology and holographic interference method.
