Ping Zhou, James H. Burge College of Optical Science, University of Arizona, 1630 E.

This paper addresses errors due to diffraction effects in inter...

The last few years have seen major advances in laser interferometry. The use of laser diodes whose output wavelength can be controlled by varying the injection current has led to the development of several new techniques in interferometry, as well as new methods for multiplexing fiber-interferometer sensors. New fields have also been opened up by phase-conjugate interferometers and the use of s...

For health monitoring of a building, we need to separate the response of the building to an earthquake from the imprint of soil-structure coupling and from wave propagation below the base of the building. Seismic interferometry based on deconvolution, where we deconvolve the wave fields recorded at different floors, is a technique to extract this building response and thus estimate velocity of ...

We generalize the traditional concept of temporal optical interferometry to any degree of freedom of a coherent optical field. By identifying the structure of a unitary optical transformation that we designate the generalized phase operator, we enable optical interferometry to be carried out in any modal basis describing a degree of freedom. The structure of the generalized phase operator is th...

Polarimetric Interferometric Synthetic Aperture Radar (PolInSAR) is a new trend of SAR remote sensing technology which combined polarized multichannel information and Interferometric information. It is of great significance for extracting DEM in some regions with low precision of DEM such as vegetation coverage area and building concentrated area. In this paper we describe our experiments with ...

Although SU(1,1) interferometry achieves Heisenberg-limited sensitivities, it suffers from one major drawback: Only those particles outcoupled from the pump mode contribute to the phase measurement. Since the number of particles outcoupled to these "side modes" is typically small, this limits the interferometer's absolute sensitivity. We propose an alternative "pumped-up" approach where all the...

We use a recently derived result to extract from two-pion interferometry data from pp̄ collisions the radius of the coherent component in the source. We find a coherent source radius of about 2fm. PACS numbers: 25.75. -q, 25.70. Pq, 25.70 Gh. Two-particle Bose-Einstein interferometry (also known as Hanbury Brown-Twiss intensity interferometry) as a method for obtaining information on the space-t...

Ge-on-Si plasmonics holds the promise for compact and low-cost solutions in manipulation of THz radiation. We discuss here plasmonic properties doped Ge bow-tie antennas made with a low-point cost CMOS mainstream technology. These display resonances between 500 700 GHz, probed by time domain spectroscopy. show surface functionalization thin layer α-lipoic acid that red-shifts antenna about 20 G...
