In this paper, we introduce Internet Photonic Sensing (IPS), a new framework for deformation and vibration measurement and monitoring based on signals that are available from standard fiber optic communication hardware deployed in the Internet. IPS i

A field test that was conducted at Garner Valley, California, on 11 and 12 September 2013 using distributed acoustic sensing (DAS) to sense ground vibrations provided a continuous overnight record of ambient noise. The energy of ambient noise was con

A source-synchronous filter for uncorrelated receiver traces from a swept-frequency seismic source

Autor: N. E. Lord, Herbert F. Wang, Dante Fratta

Publikováno v: GEOPHYSICS. 81:P47-P55

We have developed a novel algorithm to reduce noise in signals obtained from swept-frequency sources by removing out-of-band external noise sources and distortion caused from unwanted harmonics. The algorithm is designed to condition nonstationary si

Publikováno v: Journal of Analytical Atomic Spectrometry. 30:1207-1213

A large radius secondary ion mass spectrometer (SIMS) has been used for in situ stable isotope analyses of geological samples at the scale of 1–10 μm. However, the original reflected light microscope of the CAMECA IMS 1280 SIMS had an optical reso
