Abstract: A system for evaluating subject objects includes at least one physical source operable to emit electromagnetic energy and driver electronics drivingly coupled to at least one physical source. The driver electronics is configured to drive at least one physical source as a number of logical sources, using an electromagnetic forcing function. The number of logical sources is greater than the number of physical sources. In addition, the system includes a sensor configured to receive an electromagnetic response from at least a portion of an evaluation object illuminated by one or more physical sources operated as logical sources, and convert the electromagnetic response to a test response signal indicative of the electromagnetic response of the evaluation object.

Abstract: A virtual image is registered among a perceived real world background. Tracking light is scanned into the real world environment, which includes at least one detector pair. A first time and a second time at which the tracking light impinges on the first detector is detected, in which the first time and second time occurs within adjacent scan lines. A time at which a horizontal scan line edge (e.g., beginning of scan line or end of scan line) is encountered is derived as occurring one half way between the first time and the second time. The horizontal location of the first detector then is determined within a specific scan line inferring the scan line edge time. The vertical location of the detector is determined within a scan frame by measuring time duration using the beginning of the frame. By determining a location independently from the temporal resolution of the augmented imaging system, the temporal location of the detector is identified to a sub-pixel/sub-line precision.
