The FPGA Implementation of Digital Correlator in PCS
Digital correlator play an important role for Photon Correlation Spectorscopy. In this paper, the theory of Photon Correlation Spectorscopy (PCS) and the internal structure of digital correlator are described, and by increasing the number of channels to improve the precision. The digital correlator with 256 channels is implemented by FPGA, effectively raising the real-time and precision.
