POLE-LIKE OBJECTS RECOGNITION FROM MOBILE LASER SCANNING DATA USING SMOOTHING AND PRINCIPAL COMPONENT ANALYSIS
Mobile Laser Scanning Object Recognition Laplacian Smoothing Point Clouds Principal Component Analysis Pole-like Objects
2014/6/5
With the spread of the Mobile Laser Scanning (MLS) system, the demands for the management of road and facilities using MLS point clouds have increased. Especially, pole-like objects such as streetligh...
Highly Sensitive Optical Line Checker with a Leaking Component Embedded on an Optical Fiber Cord
Optical Fiber Cord Leaking Component Highly Sensitive
2015/5/15
We have developed a practical optical line checker to judge whether fiber line is live or dark without any transmission failure, achieving detectable optical signal lower limit of -40 dBm in a wide wa...

Reducing the Optical Component Cost for Future Fibre Access
Optical Component Cost Future Fibre Access
2015/7/15
Next generation fibre access will require components with performance comparable to today’s long-haul DWDM but at GPON prices. This paper outlines the role of “colourless” technology and photonic inte...
An investigation of the effect of intermediate layer in three-component planar photonic crystal waveguides
three-component planar photonic crystal waveguide
2011/5/6
The introduction of a third component into planar photonic crystal waveguides definitely influences the properties of linear defect modes, such as the band diagram, intrinsic loss, group velocity and ...
Polarization Demultiplexing Based on Independent Component Analysis in Optical Coherent Receivers
Polarization Demultiplexing Independent Component Analysis Optical Coherent Receivers
2015/7/30
A novel independent component analysis based algorithm is proposed for polarization demultiplexing. It solves the converge-to-same-source problem of constant modulus algorithm while possesses similar ...
