infrared (IR) beams through the atmosphere to obtain optical communications. Like fiber‚ Free Space Optics (FSO) uses lasers to transmit data‚ but instead of enclosing the data stream in a glass fiber‚ it is transmitted through the air. Free Space Optics (FSO) works on the same basic principle as Infrared television remote controls‚ wireless keyboards or wireless Palm® devices. How Free Space Optics (FSO) Works Free Space Optics (FSO) transmits invisible‚ eye-safe light beams from one "telescope"

inflatable photovoltaic gossamer structures with concentrator lens or solar heat engines which collects‚ focuses the sun ’s energy on solar pods and transmits with the help of wireless energy transmission i.e. Microwave transmission (MWT) or by Laser Beam transmission is examined. The idea of positioning of the receivers in deserts so that there is no interference in transmission and the main role of rectenna in conversion of energy is studied. This study discusses about the main technical challenge

Microvision Inc. has the exclusive license to commercialize the VRD technology. This technology has many potential applications‚ from head-mounted displays (HMDs) for military/aerospace applications to medical society. The VRD projects a modulated beam of light (from an electronic source) directly onto the retina of the eye producing a rasterized image. The viewer has the illusion of seeing the source image as if he/she stands two feet away in front of a 14-inch monitor. In reality‚ the image is

effective the communication is ! Presently in the twenty-first centaury wireless networking is gaining because of speed and ease of deployment and relatively high network robustness. Modern era of optical communication originated with the invention of LASER in 1958 and fabrication of low-loss optical fiber in 1970. When we hear of optical communications we all think of optical fibers‚ what I have for u today is AN OPTICAL COMMUNICATION SYSTEM WITHOUT FIBERS or in other words WIRE FREE OPTICS. Free

Ghattas The differences between LED and Laser Transmitters LED LED (Light-Emitting Diode) is a two-lead semiconductor light source. It resembles a basic p-n junction diode (is a boundary or interface between two types of semiconductor material‚ p-type and n-type‚ inside a single crystal of semiconductor.‚ which emits light when activated.
