The Fringe Detection Laser Metrology for the GRAVITY Interferometer at the VLTI
, 2010 Interferometric measurements of optical path length differences of stars over large baselines can deliver extremely accurate astrometric data. The interferometer GRAVITY will simultaneously measure two objects in the field of view of the Very Large ...

Remote SensingCharacterizing both the CO2 distribution and wind dynamics in the Martian mesosphere and lower thermosphere is vital for planetary atmospheric science and mission planning. In this work, we propose a novel dual-channel passive limb-viewing imaging system designed to simultaneously observe partial CO2 column density and line-of-sight (LOS) wind speed ...

Abstract This paper presents the findings of a comprehensive non-invasive monitoring survey of the reservoir in the Beppu hot spring area, which has the largest discharge and the highest average temperature among hot springs in Japan. Interferometric synthetic aperture radar (InSAR) indicates a settlement of 15 mm over the past decade, even in ...

Temporal Variations of Crustal Properties in Northern Chile Analyzed with Receiver Functions and Passive Image Interferometry [PDF]
, 2014 This thesis analyzes temporal variations of crustal properties in northern Chile. The seismic broadband stations of the Integrated Plate Boundary Observatory Chile which started operating in 2006 deliver the data for this work. In the neighborhood of the seismic stations a MW 7.7 earthquake occurred near Tocopilla on 14 November 2007 at 52 km depth ...

Abstract. In this study, we present an innovative method to image the inner structure of orthomagmatic ore deposits using P-wave coda of regional seismic events. We combine data processing and interpretation schemes from conventional passive seismic interferometry and teleseismic receiver function (RF) method.

Abstract This paper presents a method for studying the structure of the subsurface in hard rock terrains by interferometry of the Pn-wave coda of the regional seismic events. Using theoretical background and application examples of the teleseismic coda wave interferometry and the teleseismic receiver function methods, we developed data ...
