Head-mounted or helmet-mounted displays (HMDs) have long proven invaluable for many military applications. Integrated with head position, orientation, and/or eye-tracking sensors, HMDs can be powerful tools for training. For such training applications as flight simulation, HMDs need to be lightweight and compact with good center-of-gravity characteristics, and must display realistic full-color imagery with eye-limited resolution and large field-of-view (FOV) so that the pilot sees a truly realistic out-the-window scene. Under bright illumination, the resolution of the eye is approximately=300 mu r (1 arc-min), setting the minimum HMD resolution. There are several methods of achieving this resolution, including increasing the number of individual pixels on a CRT or LCD display, thereby increasing the size, weight, and complexity of the HMD; dithering the image to provide an apparent resolution increase at the cost of reduced frame rate; and tiling normal resolution subimages into a single, larger high-resolution image. Physical Optics Corporation (POC) is developing a 5120 x 4096 pixel HMD covering 1500 x 1200 mr with resolution of 300 mu r by tiling 20 subimages, each of which has a resolution of 1024 x 1024 pixels, in a 5 x 4 array. We present theory and results of our preliminary development of this HMD, resulting in a 4k x 1k image tiled from 16 subimages, each with resolution 512 x 512, in an 8 x 2 array.
