Paper Abstract

We mainly study on hardware design and implementation of multiplexing photon correlator based on FPGA and the graphical user interface programmed by LabView to control it, and its application in submicron particle size analyzer. The study is based on the verification of the principle of sampling correlation calculation, the implementation of the multiplexing correlation operation, the hardware design of FPGA, and etc. Multiplexing photon correlator can calculate the auto-correlation function of multiplexing photon signals that were received by a single PMT at different times. Multiplexing photon correlator mainly composes of signal control module, photon counter module, shift register module, multiplier-accumulator module, communication module, etc. With appropriate optical set-up, it will change from the traditional measurement of the single point to the 2D or 3D measurement using a single photon detector, greatly expands the application range of photon correlation spectroscopy.
