Coherent Wind Measurement Data Acquisition Card
The coherent wind measurement data acquisition card features ultra-high sensitivity and temporal resolution, which can accurately detect and count the arrival time and energy of individual photons. Based on FPGA chips and high-speed digital signal processing technology, this product acquires signals received by lidar and transmits the collected pulse count signals to the upper computer. It supports a sampling frequency up to 500 MHz and adopts an Ethernet communication interface, delivering high-speed data acquisition and transmission with convenient and efficient operation.
Equipped with multiple trigger modes and flexible data acquisition configurations, the card can meet the application requirements of wind power lidars and ground-based, ship-borne, airborne meteorological coherent wind lidars.
