1. An optical communication system comprising:
- a source of optical energy to propagate optical energy along an optical path;
a detector positioned in the optical path; and
an optical system having an arcuate surface and a holographic transform function disposed within a volume of the optical system, with the optical system being disposed to filter the optical energy in accordance with properties of the holographic transform function to remove optical energy having unwanted characteristics, defining transformed optical energy, and refract the transformed energy in accordance with properties of the arcuate surface to impinge upon the detector.

Abstract
An optical communication method and system that features concurrently refracting and filtering, employing a holographic transform function, optical energy to impinge upon an optical detector with unwanted characteristics of the optical energy being removed. To that end, the system includes a source of optical energy to direct optical energy along a path, an optical detector disposed in the path, and an optical apparatus. The optical apparatus includes a lens having an arcuate surface and a holographic transform function recorded throughout the volume of the lens.
