    Hamid Hemmati is an Engineering Director at Facebook Inc. Prior to that he was with the JPL-NASA-Caltech for 28 years working primarily on satellite laser communications technology. From to he worked at the NASA Godard Space Flight Center on the COBE spacecraft and on free-space laser communications. This laser isQ-switched by a free space acousto-optic energy up to μJ with a pulse width of ns at a repetition rate of Hz is achieved for a cavity optical length of 6.

      As part of NASA’s Optical Communication and Sensor Demonstration (OCSD) program, Aerospace has built a CubeSat to demonstrate this technology–called the AeroCube Aerospace’s design is a unit CubeSat that is 10x10x15 cm and weighs about kg. Each CubeSat carries a laser hard-mounted to its body.   Explore Free Space Laser Communications with Free Download of Seminar Report and PPT in PDF and DOC Format.

Arun K. Majumdar, in Optical Wireless Communications for Broadband Global Internet Connectivity, Optical Wireless Communication Technologies. FSO communication [2] is considered to be one of the key technologies for realizing very-high speed multi-Gb/s large-capacity aerospace communications.

FSO lasercom uses lasers as signal carriers and can provide a line-of-sight. Usage and technologies. Free-space point-to-point optical links can be implemented using infrared laser light, although low-data-rate communication over short distances is possible using LEDs. Infrared Data Association (IrDA) technology is a very simple form of free-space optical communications.

On the communications side the FSO technology is considered as a part of the optical wireless. Abstract. Free-Space Laser Communication Technologies XXIII Hamid Hemmati Editor 26â 27 January San Francisco, California, United States Sponsored and Published by SPIE Volume Proceedings of SPIE, X, v.

Laser communication in space is free-space optical communication in outer space. In outer space, the communication range of free-space optical communication is currently of the order of several thousand kilometers, suitable for inter-satellite has the potential to bridge interplanetary distances of millions of kilometers, using optical telescopes as beam expanders.

Laser communications is almost perfect for use in space. It requires less power, is lighter, and has faster data rates than radio communications. Within 10 years I expect that most, if not all space-to-space communications will be done with lasers.

If you're an engineer, you need to start learning about this new, exciting technology s: 1. Free-space laser communications, also referred to as optical communica tions, is a popular subject in today's technological marketplace. A number of conferences on this subject have been organized by professional societies such as SPIE (the International Society of Photo Optical and Instrumenta tion Engineering), OSA (Optical Society of America), and IEEE (Instituteof Electrical and Reviews: 2.

Laser communications systems work similarly to fiber optic links, except the beam is transmitted through free space. In Laser Communication the transmitter and receiver must require a line-of-sight conditions and Laser communications systems have the benefit of eliminating the need for broadcast rights and buried cables.

They work similarly to fiber optic links, except the fact that, in lasers, beam is transmitted through free space. “ 6. Free Space Laser Communication Transmitting information via a laser beam Video Data Sound Terrestrial / Space based systems 7.Free space laser communications Abstract: Summary form only given.

Increased data transfer demands, limited RF spectral allocations, and emphasis on smaller spacecraft platforms to keep launch costs down are forcing space mission planners to consider free-space optical communications for their space-ground and intersatellite communications links.Raytheon’s latest Free-Space Optical Communication technology is rewriting the book on laser-driven, high-speed data transfer.

Free-Space Optical Communication technology is nothing new. Challenges to FSO capability until now have been a challenge to overcome. Commercial-grade systems are expensive and.
