英文摘要: Statistical properties of triple-random-modulated dynamic speckles (TRMDS) are studied theoretically and experimentally. The spatiotemporal correlation function of the intensity fluctuation of the speckles is obtained; it is a Gaussian distribution. The correlation time is inversely proportional to the velocity of the moving diffuser. The average radius of TRMDS is smaller than that of single-random-modulated dynamic speckles (SRMDS). The correlation time of SRMDS is approximately 70-80 times longer than that of TRMDS. The theoretical results are consistent with the experimental results.
