Abstract: A method of identifying at least one target includes receiving a series of images over time of pulsed energy reflected from the at least one target, each image including a plurality of pulses related to different first and second pulse codes, detecting the pulses in an image of the received images, and outputting pulse detection information including XY coordinates and arrival time information associated with the respective detected pulses. The method further includes associating the pulse detection information with the first and second pulse codes based on the arrival time information, and generating output position information for the at least one target in space that indicates output positions for the at least one target based on the XY coordinates and being associated with the corresponding first and second pulse codes.

Abstract: A non-transitory computer readable medium including computer executable instructions for performing a method that includes locating a pulsing laser on an imaging array, defining a sub-region array smaller than the imaging array based on a location of the located pulsing laser such that the pulsing laser is at least partly within the sub-region, and sampling the sub-region array at a sub-region sampling rate that is higher than a remainder region sampling rate.

Abstract: An imaging method includes receiving electromagnetic radiation at a focal plane array of a handheld device. The electromagnetic radiation is processed within the handheld device, and visible images are displayed on the handheld device. The displayed visible images are indicative of a scene, and include a designator and a designator identifier when a high frequency laser pulse is in the scene. The designator and designator identifier represent the high frequency pulsed electromagnetic radiation received by the focal plane array when a high frequency pulse is present in the scene.

Abstract: A method includes correcting for at least one of gain and offset during frame integration for photodetector events. Gain and offset correction is performed separately in each pixel of a digital read-out integrated circuit (DROIC) for a plurality of corresponding pixels in a photodetector array. First and second binary counters respectively use a gain register and an offset register to implement gain and offset correction.

Abstract: A pulse repetition frequency detector, tracker, and decoder includes a two-dimensional InGaAs FPA of photodetectors configured to convert laser signals into electrical signals. A ROIC is operatively connected to the InGaAs FPA to condition electrical signals from the InGaAs FPA. A module is operatively connected to the ROIC to decode pulsed codes in the conditioned electrical signals and to provide output for tracking decoded laser spots in two-dimensional space. In another aspect, an imaging device includes an imager with an imaging FPA operatively connected to a first ROIC for imaging. A pulse repetition frequency detector, tracker, and decoder including a second ROIC as described above, is operatively connected to the first ROIC. The first and second ROICs are operatively connected to correlate the position of decoded laser spots in images from the imaging FPA.
