摘要
阐述了无线激光通信的基本原理,将无线激光通信技术与密立根油滴实验仪结合,实现油滴视频信号的的无线传输。研究表明原始信号和解调信号的波形和显示图像非常一致,用无线激光传输油滴的视频图像信号质量可靠。该实验系统可推广到其他微观测量实验中,用于物理实验演示,增强实验演示效果。
The basic principle of laser communication is presented in the paper,the video signal of oil is wirelessly transmitted by the milikan oil drop instrument combination with laser communication technology.The study show that the waveforms and video images of demodulated signals are consistent with that of original signal,the transmission quality of laser communication is reliable.This system also can be used in other micro-scale measuremental experiments to enhance their demonstrating effect.
