Abstract
Aspects and embodiments are generally directed to active imaging systems and methods. In one example, an active imaging system includes a positioning system configured to detect a direction of motion of the imaging system relative to a scene, an optical source positioned to emit electromagnetic radiation, a non-mechanical beamsteering device positioned to receive the electromagnetic radiation from the optical source and configured to scan the electromagnetic radiation over at least a first portion of the scene within an instantaneous field-of-view of an optical receiver, and the optical receiver positioned to receive reflections of the electromagnetic radiation from at least the first portion of the scene within the instantaneous field-of-view, wherein the first portion of the scene is within a first edge region of the instantaneous field-of-view of the optical receiver, the first edge region being in the direction of motion of the imaging system.
