ABSTRACT:
An improved imaging technique is disclosed wherein an output from an IR-FPA (16) corresponds to image motion, wherein a scene image stays correlated with the IR-FPA readout, and wherein non-uniformities (e.g., fixed pattern spatial noise) are uncorrelated from frame to frame. The uncorrelated fixed pattern spatial noise is identified and removed by a signal processor, such as a SB-NUC block (24). The scene image is scanned over the IR-FPA by a dither mirror (14) in synchronism with the movement of a frame of pixels (17) on the IR-FPA. Electronics (16a, 16b, 30, 32, 34) are included on the IR-FPA for controlling the scanning and read out of pixels within a currently selected frame.
