Abstract: An integrated focal plane provides two co-aligned, overlapping pixel arrays in two formats, one with large pixels and low pixel count, the other with small pixels and high pixel count. Typically, the large pixels are 10 to 100 times larger in area than the small pixels. The dual arrays are disposed in a single detector substrate flip-chip bonded to a single readout circuit. They are sensitive to two infrared colors, one shorter and one longer wavelength band. The dual array focal plane concurrently provides two distinct pixel instantaneous fields of view within the same overall field of view as well as simultaneous fast and slow frame rates. The dual frame rates allow for combined fast sensing with sensitive imaging. Differing spatial and temporal data enables enhanced image processing for improved clutter rejection and detection performance. Differing gains combined with the dual frame rates provide an extended dynamic range.

Abstract: A pixel interconnect circuit that can be added to a focal plane array to enable subpixel location capability (subpixel sensing) for an imaged point source, facilitating very high frame rate operation. The pixel interconnect is typically added as a circuit component within the readout integrated circuit. The interconnect function can be turned on or off flexibly. It allows very low pixel count arrays, such as 128×128 pixels, to achieve the positional accuracy of multi-megapixel arrays. In turn, these small arrays can be clocked at very fast frame rates for enhanced threat and fast event detection. Existing systems can be upgraded by adding the pixel interconnect, which will greatly improve tracking and position accuracy without increasing data processing requirements. By modifying the focal plane while leaving other components unchanged, the pixel interconnect provides an economical upgrade for threat warning and tactical sensor systems.
