Patent CA-2298454-A1 (CA)
Inventor: GULUNAY NECATI
IPC: G01V1/36
Filed: 2000-02-16
Abstract: Marine seismic data sets are generally under-sampled spatially because of the relatively long listening times required in deep water. It is customary to use very long spreads in the field thereby enhancing aliasing and interference from coherent noise. A seismic-signal data processing method is proposed that applies a combination of a forward parabolic Radon transform and a linear Radon transform to the data, followed by a further transform to a three-dimensional frequency domain. In this domain, a deterministic operator is applied to the data to sharpen the Radon-domain response thereof.      The data are then scavenged of noise in the Radon domain and inversely transformed back into the time-space domain.

Patent CA-2320037-A1 (CA)
Inventor: BEIERL OTTMAR
IPC: G01R15/24
Filed: 1999-02-11
Abstract: The invention relates to a method for measuring a magnetic field with the aid of the Faraday effect, wherein light is injected into a Faraday element (4) arranged in a magnetic field, said light having a first linearly polarized light segment (Pa) with a first wavelength and a second non-polarized light segment (Pb) with a second wavelength differing from the first. A light signal is then decoupled from the Faraday element (4). Said light signal is optically split into a first light signal segment (LSa) with the first wavelength and a second light signal segment (LSb) with the second wavelength. A first measuring signal (Sa) is derived from the first light signal segment (LSa) and a second measuring signal (Sb) is derived from the second light signal segment (LSb), which are used to form a corrected measuring signal (S). The influences of attenuations in the transmission paths can be compensated for to a large extent even when a time constant magnetic field or a magnetic field with a time constant segment are measured.
