Paper Abstract

As three-dimensional (3D) techniques continue to evolve from their humble beginnings-nineteenth century stereo photographs and twentieth century movies and holographs, the urgency for advancement in 3D display is escalating, as the need for widespread application in medical imaging, baggage scanning, gaming, television and movie display, and military strategizing increases. The most recent 3D developments center upon volumetric display, which generate 3D images within actual 3D space. More specifically, CSpace volumetric display generates a truly natural 3D image consisting of perceived width, height, and depth within the confines of physical space. Wireframe graphics enable viewers a 360-degree display without the use of additional visual aids. In this paper, research detailing the selection and testing of several rare earth, single-doped, fluoride crystals, namely 1%Er: NYF4, 2%Er: NYF4, 3%Er: NYF4 , 2%Er:KY3F10, and 2%Er:YLF, is introduced. These materials are the basis for CSpace display in a two-step twofrequency up-Conversion process. Significant determinants were tested and identified to aid in the selection of a suitable medium. Results show that 2%Er: NYF4 demonstrates good optical emitted power. Its superior level of brightness makes it the most suitable candidate for CSpace display. Testing also proved 2%Er: KY3F10 crystal might be a viable medium.
