According to EE Times, an Israeli company has developed a personal video display device that looks like a simple pair of glasses. You can use these glasses with various sources, such as a portable media player or your cell phone. This technology promises to eliminate the dizziness phenomenon usually associated with this kind of display. And with these glasses weighing only about 40 grams, you'll feel that you're viewing a 40-inch screen from a distance of 7 feet. Read more?Here is how this technology works. Mirage Innovations Ltd.'s technology is based on the principle of transforming a thin transparent plate into a complete wearable personal display system. The diffractive planar optics is combined with a microdisplay source, such as micro LCD, LCOS or OLED.
Within the NanoPrism diffractive planar optics device, light emerging from the microdisplay source is collected by a lens and coupled into a thin transparent substrate via a nanoscale diffraction grating. The trapped light propagates within the substrate by internal reflection toward the viewer's eyes, producing a perfectly aligned image.
