Moreover, certain military activities such as night aviation maneuvers demand the most sophisticated night imaging devices.

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.
