Systems and Methods for Adjusting Movable Lenses in Directional Free-Space Optical Communication Systems for Portable Electronic Devices

Abstract:

A directional free-space optical communication system includes a source device including a laser diode and an endpoint device including a photodiode. The endpoint device and the source device also include an adjustable optics subsystem that increases both angular and positional offset tolerance between the source device and the endpoint device.
