Ground and Volume Decomposition as a Proxy for AGB from P-Band SAR Data

open access: yesRemote Sensing, 2020
In this work, the role of volume scattering obtained from ground and volume decomposition of P-band synthetic aperture radar (SAR) data as a proxy for biomass is investigated. The analysis here presented originates from the BIOMASS L2 activities, part of

Interference of Clocks: A Quantum Twin Paradox [PDF]

open access: yes, 2019
The phase of matter waves depends on proper time and is therefore susceptible to special-relativistic (kinematic) and gravitational time dilation (redshift).

Atom interferometry with trapped Bose-Einstein condensates: Impact of atom-atom interactions [PDF]

open access: yes, 2010
Interferometry with ultracold atoms promises the possibility of ultraprecise and ultrasensitive measurements in many fields of physics, and is the basis of our most precise atomic clocks.

AVALIAÇÃO DA PRECISÃO VERTICAL DOS MODELOS SRTM PARA A AMAZÔNIA [PDF]

open access: yesRevista Brasileira de Cartografia, 2006
This paper describes an experiment for evaluation of the vertical precision of the SRTM’s DEM of the C band of interferometric SAR which was compared with the Topography Chart’s DEM 1:100 000 and the GPS field points.

Simulation of anyonic fractional statistics of Kitaev's toric model in circuit QED

open access: yes, 2011
Since the anyonic excitations in the Kitaev toric model are perfectly localized quasiparticles, it is possible to generate dynamically the ground state and the excitations of the model Hamiltonian to simulate the anyonic interferometry.

A Comparison of Delayed Self-Heterodyne Interference Measurement of Laser Linewidth Using Mach-Zehnder and Michelson Interferometers

open access: yesSensors, 2011
Linewidth measurements of a distributed feedback (DFB) fibre laser are made using delayed self heterodyne interferometry (DHSI) with both Mach-Zehnder and Michelson interferometer configurations.

Interferometry from Space: A Great Dream

open access: yes, 2014
During some thirty years, 1980-2010, technical studies of optical interferometry from instruments in space were pursued as promising for higher spatial resolution and for higher astrometric accuracy.

Fluorescence interferometry

open access: yes, 2010
We describe an interferometer based on fluorescent emission of radiation of two qubits in quasi-one-dimensional modes. Such a system can be readily realized with dipole emitters near conducting surface-plasmonic nanowires or with superconducting qubits ...

Refractive Index Compensation in Over-Determined Interferometric Systems

open access: yesSensors, 2012
We present an interferometric technique based on a differential interferometry setup for measurement under atmospheric conditions. The key limiting factor in any interferometric dimensional measurement are fluctuations of the refractive index of air ...
