摘　　要：基于可见光通信技术设计了一种视频传输装置。该装置直接将CCD摄像头输出的模拟信号作为输入信号,结合发射端与接收端的高频响应元件,实现了短距离的可见光视频传输。该装置电路响应速度高,传输100 k Hz^200 k Hz方波信号时仍无明显失真。经对比测试,传输的视频色彩丰富、细节清晰,同有线方式传输的视频相比差别较小。A video transmission device is introduced,which based on visible light communication technology. This device can use the analog signal output by CCD camera as the input signal.It realizes the wireless video transmission in short distance by combing the high frequency response elements of the transmitting and receiv- ing.The circuit of the device has a high response rate, and there is no obvious distortion when it transmits the square wave signal whose frequency is 100 kHz？200 kHz.The video transmitted has rich color and interact de- tails,and has little differences compared with it transmitted by electric cable.
