The Research of Electromagnetic Compatible Performance in Laser Shoot Synchronization System

The implementary processing means of electromagnetic compatible and the jitter compensation principle in the high-speed digital synchronization system based on the electrics theory are analyzed.For the shielding of the electric field f interference,used the metal Cu or the material Al which has high conductance and ideal shielding echo wastage R.For the shielding of the magnetic field,used the permalloy material which has high permeability and appropriate shielding echo wastage R,used the EMI filter which has small capacitance temperature coefficient and high precision,the equivalent resistance R which inductance material presents tallies with sorbed band interference.The system can achieve maximal efficiency of restrain electromagnetic interference,the experimenta prove that these means are in effect.
