Design and realization of beamforming optics for short-distance free-space optical (FSO) communications

Optica Latin America Optics and Photonics Conference (LAOP) 2024
Beamforming optics for short distance FSO links is designed and laboratory tested. The transmitting optics is designed to collimate a diverging laser beam. The receiving optics concentrates light in a fiber-pigtailed photodetector. Results are reported.

Free-space Optical (FSO) Platforms: Unmanned Aerial Vehicle (UAV) and Mobile

2014
This chapter discusses the emerging technology of unmanned aerial vehicle (UAV)-based free-space optical (FSO) communication links. UAVs are a possible future application for both civil and military use. The large amount of data generated by the UAVs requires high data rate connectivity, thus making FSO communication very suitable.

Theory of Free-Space Optical (FSO) Communication Signal Propagation Through Atmospheric Channel

2014
The goal of a communication system is to transmit information which can be accomplished in many ways. Free-space optical (FSO) technology depends on the propagation of optical beam through various media, which interact with and affect the quality of the propagating optical signal.

Non-Line-Of-Sight (NLOS) Ultraviolet And Indoor Free-Space Optical (FSO) Communications

2014
This chapter presents a new concept for exploiting non-line-of-sight (NLOS) free-space optical (FSO) communication. NLOS configuration can be achieved using scattering as a vehicle for a viable link, or using multipath propagation as in an indoor optical communication link.
