3D URBAN MODELLING WITH VRML TECHNOLOGY – COMBINATION OF 2D AND 3D INFORMATION AND INTEGRATION TO MOBILE CLIENTS
Remote Sensing GIS VRML 3D Urban Modelling
2015/9/28
A 3D representation of a city embedded in an internet environment is not a new technology. It is already used in many
projects which present tourist information. But 3D modelling assumes a lot of ma...
comparison of dem generation and combination methods using high resolution optical stereo imagery and interferometric sar data
DEM/DTM High resolution Combination Fusion Accuracy Multisensor Optical SAR
2015/9/1
Digital elevation models (DEM) from satellite data are generated mainly from two types of datasets using completely different methods: photogrammetry for optical stereo images (e.g. SPOT5, IKONOS) and...
Opto-mechanical combination of a line scanning camera and a micro laserscanner system
Panoramic camera laser scanner optical path field lens
2015/8/25
Line scanning cameras are used in photogrammetric applications to record images with a very high resolution and a field of view up to 360° horizontally. In order to generate 3D information more than o...
50-Wavelength Channel-by-Channel Tunable Optical Dispersion Compensator Using Combination of Arrayed-Waveguide and Bulk Gratings
Dispersion compensation devices Waveguides planar Gratings Spatial light modulators
2010/6/8
We propose a novel optical configuration for a channelized tunable optical dispersion compensator (TODC) with channel-by-channel operation across entire the L-band. The TODC consists of a cyclic frequ...
All-optical Combination of DPSK and OOK to 320-Gb/s DQPSK Signal Using Fiber-based Signal Processors
All-optical Combination OOK QPSK Signal Fiber-based Signal Processors
2009/7/15
All-optical combination of 160-Gb/s DPSK and OOK signals into a 320-Gb/s DQPSK signal is demonstrated using highly-nonlinear fibers. A polarization-insensitive optical parametric limiter enabled error...
Principle of the Phase Controlling of the SBS Wave and its Application to the Beam Combination Laser for the Laser Fusion Driver
Stimulated Brillouin scattering Phase control Phase conjugate mirror
2009/6/1
The phase control of the stimulate Brillouin scattering (SBS) wave by a standing wave is the most important technique for the realization of the beam combination laser system. In this work, a theoreti...
Coherent combination of laser radiations and fringe contrast ratios on far field patterns
beam combination Fourier-optics dark fringes
2008/2/5
Fourier optics method has been used to study the far field of coherently combined laser beams. And an explicit expression of the far field has been derived for the case when emitters are positioned on...
