Abstract
The SPRITE (Signal Processing in the Element) detector comprises a long thin filament of mercury cadmium telluride. The filament is divided into two sections, the integration and readout regions. Ambipolar drift speed in the filament is matched to the scanning speed in a thermal imager, and the device performs in the element the functions normally achieved with time-delay-and-integrate electronics. We consider the optimum choice of integration section length having regard to the trade-off between high and low spatial frequency performance. The readout section length can also be optimized, in this case the noise performance of the detector preamplifier is an important consideration, because both noise and responsivity of the detector fall at high frequencies.
