OSA Rochester Section

The Rochester Section of the Optical Society of America is a group of people 
in the optics industry who are interested in promoting the knowledge of optics in the local community.

The Second Century of the OSA Rochester Section
It was Novemeber 18th, 1915 when nine Rochester scientists met at the University of Rochester: four from Eastman Kodak Co., four from Bausch & Lomb, and one from the University.

Satellite Laser Ranging Technology and its Impact on Modern Science 

John Degnan 

Sigma Space Corporation

In Satellite Laser Ranging (SLR), a short laser pulse is transmitted from a ground station to an orbiting

satellite and reflected back to the station, which measures the roundtrip time of flight and hence the

station-to-satellite range. The first laser returns from an artificial satellite were recorded by a NASA team

at Goddard Space Flight Center on 29 October 1964.The satellite, Beacon Explorer 22B, was equipped

with a Laser Retroreflector Array (LRA), designed to return the laser light to its point of origin. In July

1969, the Apollo 11 astronauts placed the first LRA on the surface of the Moon; the number of lunar

LRAs was later increased to 5 by Apollo 14 and 15 and two unmanned Soviet Lunakhod missions. Over

the intervening decades, the ranging precision has improved from a few meters to a few mm and the

number of stations in the global network has increased to about 40. SLR techniques have moved beyond

lunar ranging to support a wide range of science and engineering goals including monitoring global

tectonic plate motion, mapping ocean currents, global navigations systems, satellite tracking with single

photon returns, and tests of low-power interplanetary communication systems.

OSA Rochester Section Newsletter

OSA Rochester Section sends out newsletters on occasion to keep our membership informed about our activities.  The most recent newsletter may be viewed and downloaded at the link below:

  Newsletters from previous months can be found in      the news section.

Educational Activities

The Rochester Section is active in the support of optics education in area schools. The Rochester Section developed its Optics Suitcase in 1999. The Optics Suitcase is an innovative, interactive presentation package designed to introduce middle school students to many of the concepts of optics as well as other sciences.

Information on Joining
