【摘 要】With the development of semiconductor laser technology, laser proximity fuzes have been widely used in various kinds of guided missiles and conventional ammunitions. Conventional laser proximity fuzes consisting of separated components, have the disadvantages such as large volumes and poor anti-jamming abilities, so are not satisfied with the modern warfare circumstances. Combined with the separated components, the system has been divided into transmitting module, receiving module and information processing module, the different modules have been analyzed in detail,. Meanwhile, the transmitting driven circuit has been developed and laser pulse with 20ns narrow width was obtained. In order to meet the multifunction and miniaturization, laser fuzes based on MEMS/MOEMS have been introduced in this paper. Technologies include vertical-cavity surface-emitting laser, integrated resonant-cavity photodetector and refractive micro-optics. The entire structure was roughly 1~2mm thick and 1mm on a side. 隐藏更多
