Abstract

Honeywell has developed a quantitative image quality model for the Helmet Mounted Display (HMD) electro-optical systems that will predict the optical performance and image quality of a given system configuration. The linear systems model includes modules for the image intensifier objective, image intensifier tube, fiber optic faceplates and tapers, charge coupled device (CCD) camera, liquid crystal display (LCD) or CRT image source, relay optics, electronic filtering and preprocessing, and a perception model for the eye. Sine wave and square wave system response are predicted via modulation transform function (MTF) calculations as well as the maximum resolution and a measurement of just noticeable differences (jnd's) as perceived by the human eye. The model will allow the system designer to quickly and inexpensively evaluate complex systems tradeoffs and modifications to advanced HMD systems.
