Physical Evaluation of the Integrated Helmet and Display Sighting System (lHADSS)Helmet Display Unit (HDU)

摘要

The Helmet Display Unit (HDU) of the Integrated Helmet and Display SightingSystem (IHADSS) of the AH-64 Apache helicopter was evaluated to establish baseline data for performance figures-of-merit for comparison of fliture helmet mounted display designs. Measured parameters included physical and optical eye relief, exit pupil size, and position, field-of-view, luminance range, transmittance and reflectance characteristics, and static and temporal response.
