Abstract : The Helmet Display Unit (HDU) of the Integrated Helmet and Display Sighting System (IHADSS) of the AH-64 Apache helicopter was evaluated to establish baseline data for performance figures-of-merit for comparison of future 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.
