OIL SPILL AISA+ HYPERSPECTRAL DATA DETECTION BASED ON DIFFERENT SEA SURFACE GLINT SUPPRESSION METHODS
Oil Spill Detection Hyperspectral Data Glint Suppression Wavelet Transform Enhanced Lee Filter
2018/5/16
The marine oil spill is a sudden event, and the airborne hyperspectral means to detect the oil spill is an important part of the rapid response. Sun glint, the specular reflection of sun light from wa...
Graphene surface plasmons at the near-infrared optical regime
Graphene surface plasmons near-infrared optical regime
2015/8/6
Graphene has been identified as an emerging horizon for a nanoscale photonic platform because the Fermi level of intrinsic graphene can be engineered to support surface plasmons (SPs). The current sol...
Spectral Reflectance Characteristics of Different Snow and Snow-Covered Land Surface Objects and Mixed Spectrum Fitting
Snow Snow-covered land surface object Spectral characteristics Spectral fitting
2012/4/17
The field spectroradiometer was used to measure spectra of different snow and snow-covered land surface objects in Beijing area. The result showed that for a pure snow spectrum, the snow reflectance p...
Wafer Surface Charge Reversal as a Method of Simplifying Nanosphere Lithography for Reactive Ion Etch Texturing of Solar Cells
Simplifying Nanosphere Lithography Solar Cells
2008/10/30
A simplified nanosphere lithography process has been developed which allows fast and low-waste maskings of Si surfaces for subsequent reactive ion etching (RIE) texturing. Initially, a positive surfac...
nm- and μm-Scale Surface Roughness on Glass with Specific Optical Scattering Characteristics on Demand
Specific Optical Demand
2008/10/29
During maskless ion etching of amorphous glass, self-organization can arise in certain etch parameter ranges, which leads to dense-lying dots/cones with typical diameters and heights in the 30–300R...
Design of midinfrared photodetectors enhanced by surface plasmons on grating structures
photodetectors enhanced surface plasmons grating structures
2015/8/11
The authors propose to exploit the unique properties of surface plasmons to enhance the signal-to-noise ratio of midinfrared photodetectors. The proposed photodetector consists of a slit in a metallic...
