Researchers are exploring ways to optimize the precision of laser speckle contrast imaging, a technique used for blood flow imaging and other applications. Studies are investigating various aspects of the technology, including denoising methods, the impact of light polarization, and the design of metasurfaces for improved imaging. The research also encompasses comparisons of different imaging approaches, such as handheld versus mounted devices, and the use of laser speckle contrast imaging for specific conditions, like psoriasis.
