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...
Perceiving motion while moving,or how pairwise invariants make optical flow cohere
Perceiving motion while moving pairwise invariants optical flow cohere
2015/8/13
Computer-generated sequences simulated observer movement toward 10 randomly placed poles, 1moving and 9 stationary. When observers judged their direction of movement, or heading, they used 3 related i...

Demonstration All-Optical Pattern Recognition
2015/7/30
We demonstrate all-optical pattern recognition using semiconductor optical amplifier logic gates. For the first time, target patterns up to 256 bits long were successfully recognised and located in 42...
Black phosphorus is new ‘wonder material’ for improving optical communication
Black phosphorus wonder material optical communication
2015/3/2
Phosphorus, a highly reactive element commonly found in match heads, tracer bullets, and fertilizers, can be turned into a stable crystalline form known as black phosphorus. In a new study, researcher...
A LCOS WSS implements an optical inverse Fourier transform for 10-Tb/s OFDM signal generation and cyclic prefix insertion. After 857.4 km of dispersion uncompensated transmission, a second WSS impleme...

Total Absorption in a Graphene Monolayer in the Optical Regime by Critical Coupling with a Photonic Crystal Guided Resonance
graphene photonic crystal near-infrared critical coupling guided resonance absorption enhancement
2014/8/6
We numerically demonstrate total absorption in graphene in the near-infrared and visible wavelength ranges by means of critical coupling with guided resonances of a photonic crystal slab. In this wave...
