Design of a multi- element FSO transceiver array for mobile communication links
Proc. SPIE 11678, Free-Space Laser Communications XXXIII, 1167805 (10 March 2021); doi: 10.1117/12.2582633

Key Points

  • An optimized multi-element full-duplex free-space optical (FSO) transceiver and methods for optimizing tiling patterns to ensure uninterrupted performance among mobile platforms, even in the presence of vibration and perturbance
  • Compact, cost-effective and light-weight design suitable for mounting on platforms such as unmanned aerial vehicles (UAVs, drones)

Abstract

The University of Central Florida invention is a genetic algorithm framework to explore optimized multi-element free-space optical (FSO) transceiver tiling patterns to ensure maximal signal-to-interference and noise ratio (SINR). The framework also serves to minimize the effects of vibration of the mobile platform and atmospheric turbulence. With the ever-growing demand for high-speed mobile data, smart free-space optical (FSO) communication is a critical technology due to its significantly faster data transfer rate, higher security, lower costs, and reduced power usage. This invention improves the performance of FSO communication links by multi-element tiling the laser-based transceivers, which is capable of in-band full-duplex (IBFD) communication.

Benefit

  • Faster data transfer rate, higher security, lower costs, and reduced power usage
  • Lightweight and easy to mount on mobile platforms (UAVs)
  • Maximal signal-to-interference and noise ratio (SINR)

Market Application

  • Short-range communication with potential application in inter-UAV communication
  • Home surveillance
  • Low altitude local ad-hoc communication systems
