Abstract
The Advanced Helicopter Pilotage (AHP) program is developing a wide field-of-view, night and adverse weather vision system for helicopter navigation and obstacle avoidance. THe AHP hardware consists of a second generation thermal sensor, a high definition image intensified camera, and a helmet mounted display (HMD). The specifications for next generation night vision sensor require through the system performance measures. As such, particular importance is given to the quantification of limiting resolution at operationally relevant illumination levels rather than measures performed under typical laboratory illumination.In this paper, descriptions of the AHP HMD and image intensified camera are given, and the measured modulation transfer function of the HMD is reported. Also covered are the results of noise limited resolution testing of the AHP HMD and image intensified camera. A comparison of MTF and noise limited resolution measures, made under the appropriate illumination, using a Dage HR-2000 is presented.
