Abstract
A LIDAR sensor element and system for wide field-of-view applications such as autonomous UAS landing site selection is disclosed. The sensor element and system have an imaging source such as a SWIR laser for imaging a field of regard or target with a beam having a predefined wavelength. The beam is scanned over the field of regard or target with a beam steering device such as Risley prism. The reflected beam is captured by the system by receiving optics which may comprise a Risley prism for receiving and imaging the reflected beam upon a photodetector array such as a focal plane array. The focal plane array may be bonded to and a part of a three-dimensional stack of integrated circuits, a plurality of which may comprise one or more read out integrated circuits.
