Abstract: An infrared detector and imaging system responsive to the scanned image from an objective lens and scanner system, the infrared detector and imaging system comprising: a detector substrate; a sparsely populated staggered detector array formed on the detector substrate, the detector substrate having a focal plane surface receiving the scanned image from the objective lens and scanner system. A clock means provides clock signals. A control signal means is responsive to the clock signal for providing a sequence of predetermined scanner position signals. A servo responsive to each scanner position signal commands the scanner means to locate the scanned image at predetermined positions on the focal plane. A detector signal integration means receives and integrates an array of detector signals from the sparsely populated detector array.
