On the basis of studying technology of FSO(Free Space Optical communication)and domestic、foreign fuze optical set,this paper analyzes techniques of encoding and modulation in theory and then a low power dissipate and portable fuze laser setting system was designed.

Design of laseremission unit in laser fuse;

Cloudy influence analysis of alitimetry performance of laser fuse and a solution;

In the sender of laser fuse,the factor M2 of the linear array laser cannot be measured as a single laser diode because the facular of the linear array laser diode is superposed by that of several single laser diode.

By using computer simulation technology and light scattering theory of a rough surface, the laser detonator received power is calculated,with the good agreeme nt with measurement practically.

Aimed at the lower efficiency of using inductive energy at the moment of feedback, the paper puts forward a method to realize the feedback of setting information by using load modulate through the analysis of the sub carrier wave frequency and fuze setting transmission channel technology based on sub carrier wave.

Through analyzing the mutual effect between the muzzle velocity measuring system and the fuze setting system, a muzzle velocity measuring method is provided.

According to need of the laser set fuze with low noise,high gain,low power dissipation and small volume,information receiving circuits of the laser set fuze was analyzed and a preamplifier circuit was designed.
