The Helmet-Mounted HUD: A Change in Design and Applications Approach for Helmet-Mounted Displays.
Abstract
In the past much of the effort expended in the development of Helmet-Mounted Displays (HMD) was directed toward the goal of displaying high resolution video over a wide angular field of view. These systems were not entirely acceptable from an operational standpoint due to excessive weight, size and a number of adverse visual effects related to viewing two competing, high resolution images. Recent studies at the USAF Aerospace Medical Research Laboratory (AFAMRL) have been directed at the introduction of a flexible fiber optics bundle. (FFOB) to relay alphanumeric/symbolic information from a Cathode Ray Tube (CRT) located off the helmet in order to provide Head-Up Display (HUD) equivalent display information. This approach results in less weight and size, the potential for increased brightness and the removal of high voltage from the helmet. In addition to these improved hardware characteristics several visual problems are avoided by this simple configuration. This paper will examine the rationale for such a design approach as well as present results laboratory studies to assess the effect of FFOB fiber density on symbol legibility for a Helmet-Mounted Head-Up Display (HMHUD).
