Abstract In order to improve the measurement efficiency and accuracy of multi-angle dynamic light scattering (MDLS) experiment, a multi-channel dynamic light scattering autocorrelator based on field programmable gate array (FPGA) is developed. The autocorrelator uses FPGA to sample photon pulse signals from four scattering angles at the same time, which realizes high-frequency pulse counting and autocorrelation calculation. A double counters module is designed to ensure high-frequency lossless counting. Dynamic data storage is realized by in-chip ring register combining with out-of-chip DDR3 chips. The correlation calculation module is designed by multi-tau correlator structure. The autocorrelation calculation results are transmitted through the USB communication module. Using the limited hardware resources of FPGA, the autocorrelator realizes multi-channel autocorrelation calculation, solves the storage problem of a large number of counting data, and improves the test efficiency of MDLS experiment. Polystyrene particles sized from 50nm to 200nm are used in MDLS experiment by the autocorrelator. The results are in good consistency with the nominal particle size of the sample, which shows that the system can effectively characterize the particle size.
