Lens-free motion analysis via neuromorphic laser speckle imaging.
Optics Express, 2022 Laser speckle imaging (LSI) is a powerful tool for motion analysis owing to the high sensitivity of laser speckles. Traditional LSI techniques rely on identifying changes from the sequential intensity speckle patterns, where each pixel performs ...

Direct characterization of tissue dynamics with laser speckle contrast imaging.
Biomedical Optics Express, 2022 Laser speckle contrast imaging (LSCI) has gained broad appeal as a technique to monitor tissue dynamics (broadly defined to include blood flow dynamics), in part because of its remarkable simplicity.

Speckle experiments in random lasers [PDF]
Physical Review E, 2002 We present measurements of speckle in a random laser. We analyze its first-order statistics and show that, contrary to what might be expected for passive systems, analyses of the intensity distribution P(I) and the speckle spot size do provide information about light transport inside the system. P(I) is used to determine the degree to which an incident
