Evaluation of the Microvision Spectrum SD2500 Helmet-Mounted Display for the Air Warrior Block 3 Day/Night HMD Program

Abstract

The Microvision Spectrum SD2500 HMD, a monocular, full-color scanning laser display, display, was evaluated for optical image quality. The data indicated compliance with spectral integrity, field curvature, refresh rate, luminance uniformity, distortion and exit pupil size specifications. However, the contrast transfer function and the modulation transfer function clearly showed that the system had insignificant modulation at the Nyquist frequency. The trapezoidal shaped field-of-view was determined to be noncompliant, and the loss of the left seven columns of pixels was identified as a deficiency.
