In the view of the problem on the measurement of projectile coordinate based on laser screen thatneeds massive optical signals, the design of massive optical signals acquisition and storage system is proposed. FP.GA is used as the chip of acquisition and control and FLASH is used as the chip of storage. The collected photoelec.tric signals are temporarily placed in the FPGA build-in FIFO, and then these signals are processed in the FPGAand stored in the FLASH, and USB interface is used to communicate with computer. The simulation results showthat the system could collect and store 64 digital signals successfully, it has flexible structure, simple operation, ac.curate data and large storage.
