Abstract

We present a model for QWIP-based thermal imagers which allows us to study the effects of the main system parameters on system performance. We use the model to illustrate some of the issues involved in choosing system parameters using a sensitivity analysis. We then present a methodology for choosing the optimal system parameters which takes the constraints presented to the system, such as cost, as an integral part of the model. We propose the use of a benefit- function and a cost-function that allow us to measure the cost-benefit ratio for every system. We use this ratio as the merit figure of the system and optimize for maximal cost- benefit.
