摘　　要：设计了基于FPGA的投线仪激光检测系统。选用EP2C5T144C8N(FPGA)芯片作为硬件电路主核,利用Verilog语言和C#语言设计激光采集系统的软件,实现线阵CCD和AD转换芯片的驱动以及对采集数据的实时处理和显示。最终实验结果能满足激光投线仪的检测需求。We design a laser acquisition system based on linear CCD and FPGA.The system chose the FPGA chip EP2C5T144C8N(FPGA)to be the master chip.Verilog language and C#language are used to design the system software to implement the driver of linear CCD sensor and analog-digital conversion,real-time imaging and processing of the acquired data.The experimental results show that the linear system can satisfy the demand of LDI’s detection.
