Abstract

Previous work by the Army's Night Vision and Electronic Sensors Directorate extended the Army's target acquisition performance models to include the task of facial identification in the visible band. In this work, additional field data for facial identification is used to validate the direct view optic (DVO) performance model. The target acquisition model for direct view optics is based on the contrast threshold function of the eye with a modification for the optics modulation transfer function (MTF) and the optics magnification. We also show that the current Targeting Task Performance (TTP) metric can approximate the measured data, without using the full accuracy provided by the two-dimensional specific object method described in previous work.
