Abstract
Exploiting the unique properties of holographic optical elements, a novel design for the receiver optical subsystem used in Multi-Spot Diffusing Configuration (MSDC) is proposed. With a holographic spherical mirror (HSM) as an optical front-end, the receiver would achieve significant improvements in the electrical signal-to-noise ratio compared to a bare photodetector. Though better performance could be achieved using other types of optical concentrators, the multifunctionality of the HSM, its small size, light weight, and low-cost make it a promising candidate for a user's portable equipment in broadband indoor wireless multimedia access.
