Abstract: A method to spread laser photon energy over separate pixels to improve the likelihood that the total sensing time of all the pixels together includes the laser pulse. The optical signal is spread over a number of pixels, N, on a converter array by means of various optical components. The N pixels are read out sequentially in time with each sub-interval short enough that the integration of background photons competing with the laser pulse is reduced. Likewise, the pixel read times may be staggered such that laser pulse energy will be detected by at least one pixel during the required pulse interval. The arrangement of the N pixels may be by converter array column, row, two dimensional array sub-window, or any combination of sub-windows depending on the optical path of the laser signal and the capability of the ROIC control.

Abstract: A dual-mode laser-based and image-based seeker for projectiles, missiles, and other ordnance that persecute targets by detecting and tracking energy scattered from targets. The disclosed embodiments use a single digital imager having a single focal plane array (FPA) sensor to sense data in both the image-based and laser-based modes of operation. A control mechanism controls pixel scanning at a sub-window of the FPA to tightly control the imager's shuttering to detect, decode and localize in the imager's field-of-view a known pulse repetition frequency (PRF) from a known designator in the presence of ambient light and other confusing target designators, each having a different PRF.
