Proceedings of the 4th ACM Workshop on Wearable Systems and Applications, 2018
In near future, we expect the Virtual Reality (VR) headsets to be wireless and to be demanding data-rate up to Tbps, thus pushing RF technology to the limit. In this work, we explore the possibility of using steerable Free Space Optics (FSO) to create a wireless link between a wall-mounted static transceiver and a VR headset in motion with its user. We

Forward prediction of FSO received signal for FSO/RF hybrid network
2009 International Workshop on Satellite and Space Communications, 2009The benefits of Free space Optics (FSO) motivates to use it for future high data rate demanding communication applications. However, widespread growth of the technology has been hampered by reduced availability due to weather influences on the link. The alternate is to use back up RF link for improving the availability.

2017 IEEE International Conference on Microwaves, Antennas, Communications and Electronic Systems (COMCAS), 2017
This paper presents a new framework for long range Free Space Optical communication (FSO). Motivated by the ever-growing demand for communication in 5G networks, the suggested framework tackles the natural FSO link drawbacks, commonly: complicated installation, limited range, size and pricing. The new FSO concept assumes a “best effort” model.

Food safety is more than ever dependent on data collected about food samples by means of both laboratory analysis and, more recently, non-destructive sensors. The latter emerging technologies for food safety monitoring show great promise for ensuring the quality and suitability of food.

Hybrid SAG-FSO/SH-FSO/RF Transmission for Next-Generation Satellite Communication Systems
IEEE Transactions on Vehicular Technology, 2023Recent advances demonstrate satellite communication (SatCom) as a potent enabler for future Terabit/s global connectivity. Existing SatCom systems, however, rely mostly on radio frequency (RF) transmission, whose limited available bandwidth is the main bottleneck for further data rate increases.

FSO relaying communication system
SPIE Proceedings, 2005It is general that with the distance increasing the communication quality of Free Space Optical (FSO) drops seriously, and the maximum transmitting distance is usually about 2 kilometers. In order to increase the covering range and transmission quality of the FSO system, a relaying device which is between the nodes is researched in the paper.

Wavelength agile FSO transceiver
2013 Integrated Communications, Navigation and Surveillance Conference (ICNS), 2013The design of a free-space optical (FSO) transceiver suitable for the demands of establishing reliable communication between mobile nodes such as UAVs requires the solution of difficult problems related to pointing, acquisition and tracking. To accommodate the inevitably larger misalignment conditions encountered in mobile applications, the receiver ...

Performance Analysis of FSO-SISO and FSO-WDM Systems under Different Atmospheric Conditions
2020 7th International Conference on Signal Processing and Integrated Networks (SPIN), 2020Free space optical communication (FSO) – is one of the best technology that have number of advantages such as high data rate, rapid ability to increase, free license spectrum and simple deployment. Atmosphere is the medium in FSO communication, thus efficiency of the communication system deteriorates due to atmospheric interferences.

This paper studies the possibility of using axicons in free space optics (FSO) systems. The behavior of the pseudo- Bessel beams generated by "logarithmic" and "linear" axicons, with or without stops, was analyzed through the Huygens-Fresnel integral of diffraction in cylindrical coordinates.
