ABSTRACT:
A multi-channel rotary optical coupler incorporates a multi-element lens assembly formed of a coplanar plurality of annular convex lens elements, with each lens element of the assembly having a substantially constant annular width and a discrete optical axis, with each optical axis of each lens element radially displaced about a central rotational axis of the coupler. Each lens element receives an output from a respective data modulated light source and provides discrete data channels for the continuous transmission of discrete data signals through the lens elements to respective similarly radially displaced optical detectors of a detector array.
