Design and Implementation of High Precision Synchronization Controller for Gated Imaging

Abstract

In this paper, we have designed a high-precision synchronization controller for gated imaging. The design scheme is proposed according to the semiconductor laser arrays overall range-gated imaging system composition and working principle. The programming of control logic is illustrated in detail from the main time counter, mode control logic, key control decoder, pulse generator, automatic frequency generator and display control. Finally, a synchronization controller with precision of 80 ns and frequency of 12 khz was developed. The whole system joint debugging test shows that the indicators of the synchronization controller have reached the expected goal, and have met the current technical requirements of gated imaging within 3 km in the atmospheric environment.
