Abstract

The Night Vision Integrated Performance Model (NVIPM) is a versatile tool used in conducting trade studies of EOIR imaging system performance. Although its primary application is the calculation of human performance metrics, the linear systems model and standard imaging chain provides a convenient method of modeling and validating laboratory measurements. In this correspondence, we discuss how to model signal to noise measurements for both emissive and reflective band cameras within NVIPM. We provide convenient components that can be used to model the calibrated detectors necessary in most laboratory setups. Additionally, we present an update to the measured system component in order to output in digital numbers (DN), matching the default units available to the experimentalist. Using this measured system component and the methods developed for modeling the experiment with reference detectors, we show how NVIPM is an ideal tool for demonstrating measurement and laboratory agreement.
