Göze yakın ekranlar için kompakt arka ışık aydınlatıcı

The advancements in micro-electronics, optics and fabrication during the recent decades have led to an ever rising miniaturization, personalization and mobility trend in technology. Just as the headphones that replaced loudspeakers; large televisions and monitors are getting substituted by personal and portable displays, including the wearable near to eye displays (NEDs). Immersive NEDs present users virtual reality (VR), while optically see-through NEDs present augmented reality (AR), with dozens of niche applications in entertainment, education, medical and military domains. The ultimate NED should simultaneously provide high resolution, wide field-of-view (FOV), thin form-factor, large eye box, sufficient brightness and light efficiency, which are all competing requirements. Existing solutions indeed meet merely a subset but not all of the listed objectives. In this thesis, a novel fiber based point source illuminator for near to eye displays capable of presenting wide field of view is presented. The proposed technology is suitable for both immersive (virtual reality) and optical see-through (augmented reality) applications. Proposed design is a coherent backlight illuminator that combines a fiber, scattering nanoparticles and a concave or ellipsoidal mirror which converts the wave from fiber to a converging wave. It is also possible to minimize the volume and to use the demonstrated technology in equipment where small form factor is important. The technology is also adjustable for different illumination profiles (collimated, converging, diverging etc.). Point source fabrication and three different configurations for point source usage are presented. Images captured with a computer generated holograms are presented to support the validity of the design.
