    Abstract: A system and method for enhancing laser contrast on a remote target utilizing an image processor and a laser power controller is provided. An image processor in an imaging device manipulates a laser power controller in a laser system so that a laser beam emitted from a laser system is ultimately synchronized with the imaging device. Firstly, the original laser signal is shifted one time frame relative to the plurality of time frames to create a shifted laser signal. Secondly, the shifted laser signal is subtracted from the original laser signal. Thirdly, the subtracted laser signal is magnified by a frequency band pass filter. The filtered laser signal is added to the original signal to become the finalized laser signal which has better contrast than the original signal.

    Abstract: A nondestructive system and method for high resolution thermal imaging in metal casting applications is provided to detect defects and starts with the article under test being subjected to a thermal gradient, followed by infrared images taken thereof. The creation of the thermal gradient results in any defects reacting differently to the thermal gradient application to accentuate the defect in the infrared image. The apparatus for conducting the tests in one embodiment includes a single channel sensor, remote cable, and a laptop controller with real time image processing software. This hardware provides high resolution, real-time viewable infrared (IR) images with a variable focus distance adjustable from six inches to infinity. The apparatus enables crisp, clear imagery of various metal casting defects.

    Abstract: A system and method for creating an image is presented. The system includes a first camera, a second camera, and a fusion processor. The first camera has a small field-of-view (FOV) and an optical line of sight (LOS). The second camera has a large FOV that is larger than the small FOV and the second camera has an optical LOS. The first camera and second camera are mounted so that the optical LOS of the first camera is parallel to the optical LOS of the second camera. The fusion processor fuses a second image captured by the second camera with a first image captured by the first camera. The fused image has better resolution in a fused portion of the fused image than in unfused portion of the fused image.

    Abstract: A multiple resolution focal plane array, the multiple resolution focal plane array having a plurality of bolometers and a readout integrated circuit connected to the plurality of bolometers, wherein the readout integrated circuit is configured to accumulate signal-induced current collected from each bolometer during an integration interval and then transfer the resultant signal onto output taps for readout. The readout integrated circuit is configured to allow a selection between at least two bolometer configurations, a first configuration where bolometers are combined into pixels comprising N×N series/parallel groupings of bolometers and a second configuration where the bolometers are used individually, forming pixels comprising only a single bolometer.
