An optoelectronic integrated design practice project: laser countermeasure, reconnaissance alarm, and jamming system

Abstract

Optoelectronic technology curriculum are based on optoelectronics, comprehensive use of optical technology, laser technology, analog/digital circuits and computer technology to solve various application problems. Its research contents include optoelectronic signals formation, transmission, acquisition, transformation and processing etc. The integrated design practice project is an effective way to cultivate student’s integrated application ability of multi-disciplinary theoretical knowledge. Here, An integrated design project titled “Laser countermeasure - reconnaissance alarm and jamming system” is presented. In this project, students are divided into two groups: The Blue Side and the Red Side. Laser emitting and receiving module, which consists of laser pulse coding circuit, optoelectronics receiving circuit, signal processing circuit and buzzer alarm circuit need be designed and debugged by the Blue Side. For the Red Side, which can receive the opposite radiation optics signal, encode and generate a deceptive laser which include the same coding information as the incoming laser. At last, which lead to the false alarms of Blue Side system. Also, all modules are need designed and debugged by the Red Side independently. For both sides, each group constitutes of about 4 students, project period is about 2 weeks. The practical results show that the project can deepen students' understanding of basic knowledge of optics, mechanics, electronics and computer, improve students' analysis and solving problems ability, inspire the innovation spirit and teamwork spirit.
