ONSIM: The Optical Network Simulator for Hybrid Switching Paradigms
(2019-01-11)
The elastic optical network (EON) was proposed as a solution to avoid the spectrum waste in conventional WDM networks, since it improves the network utilization. However, the elastic optical network is still based on an ...
ONSIM: The Optical Network Simulator for Hybrid Switching Paradigms
(Ieee, 2018-01-01)
The elastic optical network (EON) was proposed as a solution to avoid the spectrum waste in conventional WDM networks, since it improves the network utilization. However, the elastic optical network is still based on an ...
Antimony glasses with large nonlinear refractive indices, small two-photon absorption coefficients and ultrafast response at telecom wavelengths
(2007-12-01)
Nonlinear (NL) optical properties of antimony oxide based glasses (AG) were characterized for excitation wavelengths from 800 to 1600 m. The NL refractive indices, n2, and the two-photon absorption (TPA) coefficient, β, ...
Profilometry of semiconductor components by two-colour holography with Bi12TiO20 crystals
(2009-09-14)
We studied the shape measurement of semiconductor components by holography with photorefractive Bi12TiO20 crystal as holographic medium and two diode lasers emitting in the red region as light sources. By properly tuning ...
Pitch detection algorithms based on zero-cross rate and autocorrelation function for musical notes
(2008-09-22)
This paper discusses two pitch detection algorithms (PDA) for simple audio signals which are based on zero-cross rate (ZCR) and autocorrelation function (ACF). As it is well known, pitch detection methods based on ZCR and ...
Velocity estimation of a mobile mapping vehicle using filtered monocular optical flow
(2007-01-01)
Generally, a road image sequence acquired by a mobile mapping system (MMS) is oriented by integrating the Global Positioning System (GPS) and an inertial navigation system (INS) data. Alternatively, this article presents ...
Remote Sensing Detection of atmospheric pollutants using Lidar, Sodar and correlation with air quality data in an industrial area
(2011-11-17)
Optical remote sensing techniques have obvious advantages for monitoring gas and aerosol emissions, since they enable the operation over large distances, far from hostile environments, and fast processing of the measured ...
Re-carbonized Vitreous Carbon Substrates For Optical Applications
(IOP PUBLISHING LTDBRISTOL, 2015)
Digital control system for two-beam optical interferometry using variable structure and sliding modes method
(2019-01-01)
Laser interferometry is recognized as an extremely sensitive measurement technique, capable of detecting quantities that conventional sensors usually cannot. However, such advantage also brings a challenge, the interferometer ...
