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. ## Claims ### Claim 1 An enhanced vision system, comprising: a first optic subsystem that transmits a first scene within a field-of-view of the first optic subsystem in at least a visible portion of the electromagnetic spectrum;
