    Abstract: 본발명에따른다수의실시예들은복굴절제어를구현하는도파관들에관한것이다. 일부실시예들에서, 도파관은복굴절격자층 및복굴절제어층을포함한다. 추가실시예들에서, 복굴절제어층은컴팩트하고효과적이다. 이러한구조들은, 이로제한되는것은아니지만, 홀로그래픽도파관들에서편광관련손실들을보상하는것; 브래그격자들에기초하여도파관들에서 3-차원 LC 디렉터정렬을제공하는것; 및도파관으로부터의출력을균질화하기위해각/스펙트럼대역폭을공간적으로변화시키는것을포함하는다양한애플리케이션들에활용될수 있다. 일부실시예들에서, 편광보상을갖는편광-유지, 광각, 및고-반사도파관클래딩이복굴절격자를위해구현된다. 몇몇실시예들에서, 1/4 파또는반파지연을제공하기위한얇은편광제어층이구현된다.

    Abstract: Disclosed is an illumination system using optical feedback to maintain a predetermined illumination output. The illumination system employs an electrically controllable optical filter for filtering light incident thereon. The illumination system also includes a light detector for detecting at least a portion of the light filtered by the electrically controllable optical filter. The light detector is in data communication with the electrically controllable optical filter. Some or all light filtere d by the electrically controllable optical filter is detected by the light detector, which, in turn generates a corresponding signal that is compared to at least one predetermined value. If the signal generated by the light detector differs when compared to the a t least one predetermined value, one or more filtering characteristics of electrically controllable optical filter are varied which, in turn, varies the amount of light filtere d by the electrically controllable optical filter. The filtering characteristics of t he electrically controllable optical filter continue to be varied until the signal generated by the light detector substantially matches the at least one predetermined value.

    Abstract: A holographic display system comprising left and right optical systems is disclosed. The optical systems each comprise an image display operable to display an input image and first and second holographic devices. The first holographic device is operable to project the input image to overlap with the input image projected from the other of the left and right optical systems to form a resultant image with a first aspect ratio. The second holographic device is operable to project the input image to overlap with the input image projected from the other of the left and right optical systems to form a resultant image with a second aspect ratio, different from the first aspect ratio. A method of changing the aspect ratio of an image is also disclosed.
