摘要
A holographic optical element (HOE) device is mounted in a receiver unit, such as a wireless optical telecommunication system receiver. The HOE device includes a developed emulsion material having an interference pattern recorded thereon, sandwiched between a pair of elements, such as a pair of clear glass plates. In operation, the HOE device uses the recorded interference pattern to diffract incident light rays towards an optical processing unit of the system receiver. The optical processing unit includes a photodetector that detects the diffracted light rays. The system receiver can include various other components and/or can have various configurations. In one configuration, a plurality of mirrors is used to control the direction of the light rays coming from the HOE device, and a collimating optical assembly collimates these light rays. A beam splitting optical assembly can be used to split the light rays into a tracking channel and a communication channel.
