Abstract: Interferometric speckle visibility spectroscopy methods, systems, and non-transitory computer readable media for recovering sample speckle field data or a speckle field pattern from an off-axis interferogram recorded by one or more sensors over an exposure time and determining sample dynamics of a sample being analyzed from speckle statistics of the speckle field data or the speckle field pattern.

Abstract: A method of imaging an object on one or more sensor pixels and with reduced glare. The method includes irradiating a scattering medium and the object behind the scattering medium, creating backscattered radiation and imaging radiation that are received on the one or more pixels. The method includes digitally adjusting a phase, an amplitude, or a phase and amplitude, of reference radiation transmitted onto the one or more sensor pixels, wherein the reference radiation destructively interferes with the backscattered radiation (glare) on the one or more sensor pixels while the object is imaged on the one or more sensor pixels using the imaging radiation.
