Abstract
Laser speckle contrast imaging (LSCI), first introduced in the early 1980s (Fercher and Briers in Opt Commun 37(5):326–330, 1981), is a robust, low-cost method allowing noncontact, full-field, and real-time flow system mapping. I present an analysis of the image formation of speckles using laser sheet for fluid illumination based on convolution and Fourier techniques. I considered the Voigt distribution in the time domain to obtain a novel formula for the contrast of speckle images.
