Abstract
A method and system for imaging in degraded visual environments. The system includes a laser that is positioned to transmit a Gaussian beam toward a target object located within the degraded visual environment. An optical receiver is positioned to receive return signals. A helical phase element is positioned between the target object and the optical receiver. The return signals pass through the helical phase element. The helical phase element separates coherent and incoherent light by imparting orbital angular momentum on the coherent returns to form an optical vortex.
