Paper Abstract

The evaluation of helmet-mounted displays (HMDs) consists of optical, photometric, photographic and system performance tests that involve proper positioning and alignment of measuring tools with respect to the HMD. Evaluations are generally time consuming and involve days of meticulous testing. To shorten the time required to evaluate an HMD, we have developed a laboratory system where the positioning and alignment requirements for each test are accomplished in one step. Further, the system allows for the interchange of measuring instruments so that proper alignment is achieved as soon as the measuring instrument is mounted. In practice, the system has shortened the time required to evaluate an HMD by about 60%. The system allows for ease of position anywhere within the HMD's field-of-view (FOV). A key characteristic of the system is that the entrance pupil of the evaluation system is collocated with the HMD's exit pupil.
