This thesis examines the potential for a Chromakeyed Augmented Virtual Environment (ChrAVE), consisting only of Commercial-Off-The- Shelf (COTS) hardware, to be used as an NVG flight training platform. It also examines whether or not physically-based light calculations are necessary to produce adequate visual representation of simulated NVG imagery. Twelve subjects performed simulated low-level NVG flight navigation tasks in the ChrAVE. Treatments included questionnaires, vision tests, variation of the physics-based component of the NVG imagery, and performance of an evaluation task that compares standard thresholds between day and NVG navigation. Analysis of data and subject feedback indicate that the ChrAVE has potential as an NVG flight training device, and that physically-based calculations may not be necessary to achieve simulated NVG imagery that is adequate for training. The data also supports the existence of a substantial difference in the subjective evaluation standard between navigation performances based on flight condition. / Captain, United States Army

This study was undertaken in an effort to relate ANVIS-6 Night Vision Goggle image quality to user performance. The purpose was to determine which of five image quality metrics best related to performance tasks. The image quality metrics examined Modulation Transfer Function Area (MTFA), Integrated Contrast Sensitivity (leS), Square Root Integral (SQRI), Resolution, and Signal-to-Noise Ratio (SNR). The performance tasks were detection and recognition of targets under various levels of moon illumination. The metric that best related to target detection was SNR. The SNR results are consistent with visual psychophysics and SNR effects. The metric that best related to target recognition was Resolution. The resolution results are consistent with the position that recognition performance improves for suprathreshold targets as resolving power increases. / Master of Science

The military has invested in the development of low light level and night imaging technologies to gain tactical advantages on the battlefield. Moreover, certain military activities such as night aviation maneuvers demand the most sophisticated night imaging devices. Unfortunately, as the frequency of use of night imaging devices increases, so has the number of accidents (Boyd, 1991). Many of these accidents have been attributed to the novel usage as well as the intrinsic limitations of night imaging devices. The present research examined the effects of target size, luminance contrast, and illumination level on visual target detection and recognition while using AN/AVS-6 night vision goggles. Vehicle silhouette targets were rear-projected on random screen positions under various levels of illumination, contrast, and size. The observer's task was to detect and recognize each target while viewing through night vision goggles. The results indicate that visual detection and recognition performance degrade with decreasing levels of illumination, contrast, and target size. The findings of this work can be used to optimize the usage of AN/AVS-6 devices. / Master of Science
