Abstract
The femtosecond laser distance measurement signal data acquisition system is designed based on PCI express bus. It implements high speed data acquisition, high speed storage and PCIe bus transmission based on the method of DMA. A program of driver of the PCIe high-speed data acquisition as well as the development of the PC software is presented. The test results show that this system is stable, function complete. A variety of devices of laser distance measurement are integrated in a FPGA board.
