  • Glare suppression through fog by optical phase conjugation assisted active cancellation
    Patent number: 10194100
    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.
