HIGH RESOLUTION DISPLAY MEDIA
Abstract
An extensive non-mathematical introductory discussion is given of factors involved in image quality, including aperture response and transfer characteristics. There follows a study of the properties of commercial translucent projection screen materials and specialized techniques, with a study of experimental screen materials made of optical fibers. Commercial screen brightness distribution is improved for a 90 degree audience by combining with a Fresnel lens. One of the fiber optics experimental materials approaches the performance of such a combination. If the Fresnel lens is not used with commercial materials, fiber optics materials may give substantially equal or better performance than the best commercial screens. Studies are reported of electroluminescent image intensifier panels and photochromic materials as display media. The present state of the art in fiber optics magnifiers is reviewed. A study is presented of other possible magnifiers of this type, and the problems that may be expected. Results are given of a research into the problems of providing a large viewing angle and maintaining high resolution in a fiber optics display structure, by terminating each individual cladded fiber in an optically isolated diffusing element.
