Design of a High-speed Data Acquisition System Based on FPGA for Laser Radar

Design of FPGA-Based Data Acquisition System for the Interferometer

“…In the data acquisition system, all logic control is realized by hardware programming, which lowers the complexity of peripheral circuits, and simplifies the circuit structure. Thus, the size of the circuit can be considerably reduced and the circuit speed is then enhanced, making it possible for the construction of an online programmable data acquisition system (Liu, & Wang, 2011;Xin, Li, Hua, Song, Di, & Zhou, 2012). After collimation and beam expansion, He-Ne laser signal passes through the silicon photoelectric detector whose output signal is a weak electrical signal with noise.…”
