Study on the Emission Source of Laser Video Communication

Article Preview

Abstract:

Laser communication with its unique features was more and more get the people’s attention. The emission source of the laser video communication system was studied in this article. The emission source included laser, driver circuit, modulation circuit and filter circuit. The laser model and the parameters of driving circuit were determined according to the characteristics analysis of laser communication. The modulation circuit was designed by using MC1596 chip, and the carrier circuit was designed by QFT-100MH chip. Finally, the commissioning test was carried out, the results show that laser can work stably by the driving circuit, the functions of carrier circuit and modulation circuit is also normal. Therefore, the emission source can be used for laser video communication.
