Title
(EN) Systems and methods for adjusting movable lenses in directional free-space optical communication systems for portable electronic devices
Abstract
(EN)

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.
