The system may include: at least one controllable electromagnetic radiation source configured to generate and transmit a radiation beam onto an object, resulting in a radiation spot on said object; at least one radiation sensor configured to sense and obtain radiation reflections coming back from said object, wherein the radiation beam is generated in a way that reflections from different ranges are distinguishable of each other; and an analyzer configured to analyze said radiation reflections, and determine a remedy to the radiation beam, in a case that said radiation spot does not meet predefined spot validity criteria. The method may implement the aforementioned logic in a different architecture.

Electro-optical sighting systems and methods are provided. One example includes a optical transmitter configured to emit an infrared beam along an optical path toward a target, a beam director positioned in the optical path and having a plurality of optical elements configured to direct the infrared beam and to collect reflected infrared radiation from reflection of the beam from the target, a focal plane array detector configured to receive reflected infrared radiation from the beam director, an optical phased array (OPA) positioned in the optical path between the optical transmitter and the beam director, and a controller operatively coupled to the OPA and configured to direct the OPA to defocus the infrared beam to broaden a field of view of the optical transmitter for active illumination, and focus the infrared beam to narrow the field of view of the optical transmitter for range determination and/or target designation.

An enhanced vision system includes a first optic subsystem and a transparent photodetector subsystem disposed within a common housing. The first optic subsystem may include passive devices such as simple or compound lenses, active devices such as low-light enhancing image intensifiers, or a combination of passive and active devices. The transparent photodetector subsystem receives the visible image exiting the first optic subsystem and converts a portion of the electromagnetic energy in the visible image to a signal communicated to image analysis circuitry. On a real-time or near real-time basis, the image analysis circuitry detects and identifies structures, objects, and/or individuals in the visible image. The image analysis circuitry provides an output that includes information regarding the structure, objects, and individuals to the system user contemporaneous with the system user viewing the visible image.
