Image Intensifier System Resolution Based on Laboratory Measured Parameters
Abstract
Suitability of any analytical model is entirely dependent on how well the model prediction fits the actual measured data under real conditions. The primary intent of formulating this laboratory version of an image intensifier performance model considered the following premise. If an image intensifier model cannot accurately predict laboratory measured performance (where all test conditions and parameters are controlled and known), then it cannot be viable for predicting field performance (where conditions cannot be controlled nor are well known). The report details the basis of the model and its complete derivation. The Appendix presents numerous examples that compare the model's output with actual performance data measured by observers. The reader is referred to a planned update of the NVESD Image Intensifier Performance Model to be released in early calendar year 1994. The revised performance model will include this work on limiting resolution and establish the link between limiting resolution and the traditional Minimum Resolvable Contrast utilized for the prediction of observer performance in field conditions.
