Abstract: A laser machining system and method uses a shaped laser beam, such as a long, narrow beam, and effectively scans the beam in the narrow direction across a mask having an aperture pattern. The pattern on the mask is imaged onto a moving workpiece and the patterned laser beam selectively removes material from the workpiece. The workpiece may be moved using a coordinated synchronized rotational motion. The laser may use a longer wavelength (e.g., 248 nm) and the beam may be scanned at a high rate of speed to reduce the dissipation of the residual thermal energy in the material being machined. In one embodiment, this system and method may be used to machine a complex pattern into a curved surface with relatively high resolution and high speeds.

Abstract: A system and method of laser machining rotates a workpiece about an axis of rotation, and translates the workpiece in a first direction along the axis of rotation. A mask defining a shape is translated in a second direction opposite the first direction, and a laser beam is directed at the mask such that the laser beam is scanned across the mask and at least a portion of the laser beam passes through the mask and toward the workpiece. The mask and the workpiece are translated with coordinating opposing motion to cause the laser beam to be imaged onto the workpiece with a shape or pattern corresponding to a shape or pattern defined by the mask. Rotation of the workpiece and the shape of the image on the workpiece produce different vectorial intensities such that material of the workpiece is removed to different respective depths to form a three-dimensional structure.

Abstract: A variable astigmatic focal beam spot is formed using lasers with an anamorphic beam delivery system. The variable astigmatic focal beam spot can be used for cutting applications, for example, to scribe semiconductor wafers such as light emitting diode (LED) wafers. The exemplary anamorphic beam delivery system comprises a series of optical components, which deliberately introduce astigmatism to produce focal points separated into two principal meridians, i.e. vertical and horizontal. The astigmatic focal points result in an asymmetric, yet sharply focused, beam spot that consists of sharpened leading and trailing edges. Adjusting the astigmatic focal points changes the aspect ratio of the compressed focal beam spot, allowing adjustment of energy density at the target without affecting laser output power. Scribing wafers with properly optimized energy and power density increases scribing speeds while minimizing excessive heating and collateral material damage.

Abstract: The method for estimating the drift over time of a physical operating parameter of a clock for dating seismic data samples associated with a seismic data collection node involves measuring (10) at least one quantity associated with the clock, at predetermined instants or during predetermined time periods, and applying (12), to this quantity, a predetermined non-linear law of variation of this quantity that depends on the values collected during the measurement step (10), so as to obtain an estimation of the drift over time of the physical operating parameter.

Abstract: A method for verticalizing recorded seismic data, the method including recording first data with a particle motion sensor, wherein the particle motion sensor is located on a streamer, and the particle motion sensor is configured to be insensitive to a direct current, recording second data with a gravity motion sensor, wherein the gravity motion sensor is also located on the stream, and the gravity motion sensor is configured to be sensitive to the direct current and temporally synchronous to the particle motion sensor, selecting a cost function that associates corresponding values of the first data and the second data, determining a misalignment angle from maximizing the cost function, wherein the misalignment angle describes a misalignment between corresponding axes of the particle motion sensor and the gravity motion sensor, and correcting seismic data recorded by the particle motion sensor based on the misalignment angle so that the corrected seismic data is verticalized with regard to gravity.

The invention also relates to the acquisition system and to the corresponding gateway system, and to a corresponding method.

Abstract: A seismic source having two or more operating heads with a firing chamber pressure vessel of compressed air for generating seismic oscillations at low and ultra-low frequencies (ULF) for marine seismic exploration. The multi-headed sound source increases low frequency signal in ranges from below 1 Hz to around 7 Hz to provide greater penetration of the seismic signal through complex overburden such as salt or basalt, improve velocity model building with methods such as Full Wave Inversion, improve the ability to build blocky reservoir models, and improve resolution by reducing side lobes.
