On the effective wavelength in two-wavelength interferometry

Pure and Applied Optics: Journal of the European Optical Society Part A, 1998
A discussion on the effective wavelength in two-wavelength interferometry is given. A definition, different from the commonly adopted one, is presented and its validity is discussed. By adopting this new effective wavelength the range over which lengths can be measured using interferometric techniques can be vastly increased, without introducing phase ...

Wavelength-Selective Devices

2001
A single optical fibre is capable of transporting multiple signals, each at its own wavelength. At the fibre entrance, the signals fed by a number of transmitters, each operating at a specific wavelength, are combined by a wavelength multiplexer and launched into the transmission fibre. At the fibre exit, a wavelength demultiplexer routes these signals

THE EFFECT OF WAVELENGTH ON STEREOACUITY

American journal of optometry and archives of American Academy of Optometry, 1970
ABSTRACT Stereoacuity for small, parafoveal targets as a function of difference in chromatic stimuli was determined successively with narrow band red, green and blue targets. Apparatus was a modified Howard‐Dolman, type needle alignment device with micrometer drive capable of accurate ...

Switches, Wavelength Routers, and Wavelength Converters

2005
This chapter introduces some of the basic components in WDM networks, discusses various implementations of these components, and provides insights into their capabilities and limitations. The components discussed are fixed and reconfigurable wavelength routers, optical packet switches, and wavelength converters.

On their wavelength

Early Years Educator, 2019
National Radio Day is celebrated in the US on 20 August 2019 and is not only a day to remember the invention of the radio but also to think about words and sound as a medium of communication.
