Synthetic Aperture Radar Imaging Geodesy Signal Path Delays Geodynamic Effects Pixel Localization Accuracy Stereo SAR
2014/4/24
Previous studies have demonstrated the unprecedented absolute pixel localization accuracy of the German SAR (Synthetic Aperture Radar) satellites TerraSAR-X and TanDEM-X. Now, using global navigation ...
Method for Improving the Lateral Resolution of Near-Infrared (NIR) Single Optods: Application to Subcutaneous Vein Detection and Localization
Reflectance Measurements Photon Migration Optical Diagnosis Fiber Probe Design
2013/1/30
NIR backscattering measurements using single source-detector optical probe (optods) can detect absorption areas within deep tissue layer. However, such optods, are characterized by large separation di...
OTM- and OTDR-based cost-efficient Fiber Fault Identification and Localization in Passive Optical Network
OTM Passive Optical Network OTDR-based cost-efficient Fiber Fault
2015/5/18
PON monitoring based on combined Optical Time Domain Reflectometry (OTDR) and Optical Transceiver Monitoring (OTM) is presented. The results on a 25-km 1:32 PON prove the concept and show ~0.02 dB acc...
Survivable Mapping with Maximal Physical-Layer Failure-Localization Potential in IP over Transparent Optical Networks
Networks Network survivability Network optimization
2015/6/10
Physical-layer failure-localization potential is explored in finding the survivable mapped lightpaths of IP over transparent optical networks. Numerical results show that accurate or near-accurate fai...
Detection and Localization of Defects in Monocrystalline Silicon Solar Cell
solar cell electric signals combination of electric and optical methods
2011/4/21
Near-surface defects in solar cell wafer have undesirable influence upon device properties, as its efficiency and lifetime. When reverse-bias voltage is applied to the wafer, a magnitude of electric s...
An impact of a localization of an oxide aperture within a vertical-cavity surface-emitting diode laser (VCSEL) cavity on its lasing threshold
semiconductor laser vertical-cavity surface-emitting diode laser (VCSEL)
2011/4/27
In the present paper, an impact of localization of an oxide aperture within a vertical-cavity surface-emitting diode laser (VCSEL) on its threshold operation is analyzed. As expected, a shift of the a...
