Abstract
The present disclosure provides systems and methods for processing laser speckle signals. The method may comprise obtaining a laser speckle signal from a laser speckle pattern generated using at least one laser light source that is directed towards a tissue region of a subject and a reference signal corresponding to a movement of a biological material of or within the subject's body. The method may comprise computing one or more measurements using a first function corresponding to at least the laser speckle signal and a second function corresponding to the reference signal. The method may comprise generating an output signal in part based on the one or more measurements for the function space and using the output signal to aid a surgical procedure on or near the tissue region of the subject.
