Abstract

Modeling of generic scanned imaging systems was described in previous papers. The spatial, temporal and transform domain analysis was performed based on these models. But, the response function of detectors was variation-separable. This case is unsuitable for thermal imaging systems, which use signal-processing-in-the-element (SPRITE) detectors, because of the variation-inseparable response function of the SPITE detector. In this paper, the improved model of scanned thermal imaging system of SPRITE detector is described. Based on this model, the system analysis is performed on temporal-spatial domain, and also performed on temporal- spatial-frequency domain. Furthermore, the modulation transfer function (MTF) expression of SPRITE detectors is described. With that, it is convenient to evaluate the dynamic imaging capability of scanned systems, and image transfer characteristics of SPRITE detectors.
