Filed:

Mar 9, 2004

Appl. No.:

10/796738

Inventors:

Christopher Conway - Palos Verdes Estates CA, US
Kenneth Allen - North Hollywood CA, US

International Classification:

G03B015/02

US Classification:

315291000, 315307000

Abstract:

A mobile stage lighting system configured to be positioned on a film stage and cast soft light upon subjects and objects on stage. The lighting system includes a light frame having a plurality of light sources positioned within the frame. A mobile support is positioned below the frame and enables the frame to be moved. A diffusion film is disposed in front of the plurality of light sources and an eggcrate louver is positioned adjacent the diffusion film. Panels having light-reflective inner surfaces cover the back and sides of the diffusion frame. A light control system regulates electrical power to the plurality of light sources, such that an illumination intensity of individual ones of the plurality of light sources can be varied.

International Classification:

G01V 138

Abstract:

An apparatus and method for removing the distortion in marine seismic data resulting from the motion of the ship. The ship trails one or more seismic sources and receivers and moves forward at a known velocity. The seismic sources emit seismic waves that travel through the water and reflect off interfaces between rock formations below the ocean floor. The motion of the sources and receivers introduces distortion in the recorded seismic data that can be modeled using Doppler theory. The data preferably is corrected for source motion independently from the correction for receiver motion. The seismic data is first corrected for receiver motion and then for source motion. The technique for correcting for source motion includes correlating the receiver-corrected data with a reference sweep signal, performing an F-K transform, performing an inverse F-K transform on a selected subset of the F-K transformed data, and computing appropriate correction filters for the data resulting from the inverse F-K transform. This process is repeated for all subsets of F-K transformed data and the resulting filtered data are summed together.

Abstract:

A seismic system is provided with a method of reducing distortions caused by motion of a source and receiver in marine seismic measurements. In one embodiment, the seismic system comprises a seismic source, a seismic receiver, a source/receiver interface unit, a processing unit, a data storage unit, a display device, and a user input device. The processing unit is configured to receive seismic measurements from the seismic receiver and to create a seismic velocity model from the received data. The processing unit uses the velocity model to calculate a dilation function that is indicative of distortion caused by motion of the seismic source. Preferably, the processing unit corrects the seismic measurements for this distortion by computing a transform of the seismic measurements, partitioning the transformed measurements into "dip slices", inverse transforming the individual dip slices, correcting the dip slice measurements according to the dilation function, and adding the corrected dip slice measurements together to obtain the corrected seismic measurements. The disclosed system and method can advantageously provide for more accurate correction for source motion, which in turn yields seismic data having substantially reduced "smear" when ensemble averaging is performed to reduce seismic noise.
