Paper Abstract

Current two dimensional staring arrays of CMT detectors have very good thermal resolution, but have limited numbers of elements with present fabrication techniques. This limited spatial resolution can be increased by scanning the detector over the scene. Several techniques can be used for this including macroscan and microscan, but the experimental imager described here uses continuous scan to increase the spatial resolution. Use is made of all the detector elements by employing the CCD readout registers of a fully staring 64 x 64 CMT detector to perform a time delay and integrate (TDI) function in the scan direction.
