摘　　要：设计了16×16面阵靶板多路探测信号的采集与转贮系统电路，用于信号采集及向上位机的传送。系统采用W77E58为采集电路的CPU，以FT245BM为核心构成USB接口电路，实现了256路信号的快速采集与转贮，较好地解决了对多路探测器实时快速采集和向上位机传送的问题，从而使激光远场光斑测试系统能够实时测量远场光斑的能量分布和变化情况。The multiplex signal acquisition and transmission circuit （16 × 16 ） is designed. Using W77E58 as the CPU, and using FT245BM as the core chip in the USB interface circuit, the function of 256 paths signal acquisition and transmission is realized, and the problem of real-time acquisition and high-speed transmission in multiplex signal acquisition is solved. So it enables the measuring system to measure the energy distribution and real-time variation.
