WATER LEAKAGE DIAGNOSIS IN METRO TUNNELS BY INTERGRATION OF LASER POINT CLOUD AND INFRARED THERMAL IMAGING
Tunnel Infrared Thermal Imaging Laser Scanning Intensity Data Water Leakage Diagnosis
2018/5/16
Diagnosis of water leakage in metro tunnels is of great significance to the metro tunnel construction and the safety of metro operation. A method that integrates laser scanning and infrared thermal im...
WATER MAPPING USING MULTISPECTRAL AIRBORNE LIDAR DATA
Land Cover Classification Multispectral LiDAR Optech Titan Point Cloud Processing SLIER
2018/5/16
This study investigates the use of the world’s first multispectral airborne LiDAR sensor, Optech Titan, manufactured by Teledyne Optech to serve the purpose of automatic land-water classification with...
ON THE WAY TO WATER-TIGHT MESH
Modelling Laser scanning Cultural Heritage Robotics Automation
2015/10/8
This paper presents a new approach to generate water-tight surface mesh. In comparison with the two famous water-tight mesh
generation algorithms: Tight Cocone (Dey and Goswami, 2003) and Power Crus...

Making Hydrogen Fuel Water Visible Light Highly Efficient
2015/9/9
Mimicking photosynthesis is not easy. The bottleneck of artificial photosynthesis is visible light, because converting it into other forms of energy is not efficient. Researchers at Michigan Technolog...
Nearly Total Solar Absorption in Ultrathin Nanostructured Iron Oxide for Efficient Photoelectrochemical Water Splitting
photon management antirefl ection light trapping nanocone hematite photoelectrochemical cells
2015/8/6
We demonstrate using first-principles full-field electromagnetic simulations that nearly total above-band-gap solar absorption can be achieved in ultra-thin-film iron oxide photoanod...

2014/4/24
A new Fabry-Perot interferometer (FPI) based light-weight spectrometric camera provides new possibilities for environmental remote sensing applications. The sensor collects spectral data cubes with ad...
Oil-in-water emulsion as a modifier of water reflectance
water reflectance spectra oil emulsion
2011/5/6
The paper presents a component of the water reflectance in the visible region, stimulated by oil-in-water emulsion in the concentration of 1 ppm. A proxy for reflectance which is in use in oceanic opt...
Illumination method for high resolution imaging at water surface
optical measurement optical instrumentation optical imaging
2011/5/5
Annularly distributed light is proposed to increase the spatial resolution when observing a water
surface. When light with an annular distribution is used to illuminate the entrance pupil of
an obje...
Results of modeling of polarized phase functions (PPFs) in water polluted by oil-in-water emulsion are presented. The shapes of PPFs for various oil droplets size distributions and for two optically d...
