Omnidirectional free-space optical (FSO) receivers
SPIE Proceedings, 2007Free-space optics (FSO) is a technology that utilizes modulated light beam to transmit information through the atmosphere. Line-of-sight connection between both FSO transceivers is a necessary condition to maintain continuous exchange of voice, video, and data information. To date, the primary concentration of mobile FSO research and development has

Protocol Design for Free Space Optical (FSO) Communication
Applied Mechanics and Materials, 2015A new transceiving protocol is designed for an FSO communication system, and it’s discussed from the transmitting protocol and the receiving protocol. Different from wired communication, a FSO system modulates the data on a narrow beam of laser transmitting through the free space or the atmosphere, and the protocol is optimized for terrestrial FSO ...

Free Space Optical Communications (FSO)
2007 IEEE Avionics, Fiber-Optics and Photonics Technology Conference, 2007Free space optical communications (FSO) is now common for point to point communications between fixed locations on land, and is also used for communication between moving platforms on land, on the surface of the sea, in air, and in space. Free space implies that it is not practical to use optical fiber to connect the points that need to communicate or ...

Free Space Optical(FSO) Communication Link Design Under Adverse Weather Condition
2020 International Conference on Computer, Electrical & Communication Engineering (ICCECE), 2020This paper presents the link budget calculations for Free Space Optical (FSO) communication system under adverse weather conditions. For free space optical communication, atmospheric losses are the dominating factors in the link budget analysis. This paper discusses various factors which influence the medium between the transmitter and receiver and the

2020 European Conference on Optical Communications (ECOC), 2020
We developed a novel full-duplex FSO transceiver with optical-image stabilizer (OIS) and free-space-optical circulator. The OIS technology, which is widely used by smartphones cameras, was successfully implemented to expand the transceiver field-of-view (FOV) and maintain laser beam alignment with efficient seamless coupling to fiber core.

Incremental adaptive networks implemented by free space optical (FSO) communication
2018The aim of this paper is to fully analyze the effects of free space optical (FSO) communication links on the estimation performance of the adaptive incremental networks. The FSO links in this paper are described with two turbulence models namely the Log-normal and Gamma-Gamma distributions. In order to investigate the impact of these models we produced

A battery recharge model for WSNs using Free-Space Optics (FSO)
2008 IEEE International Multitopic Conference, 2008One of the most critical limiting factor for a Wireless Sensor Network (WSN) is its battery life. Therefore, a very desirable feature of WSN would be its rechargability to remain operational over longer period of times. However, the nodes needing recharge may not be accessible. In this paper, we present a battery recharge model in WSNs for inaccessible
