Abstract: A part defect testing system includes a hammer beam system that provides laser light having a first wavelength. A read-out beam system provides laser light having a second wavelength. A control system is used to direct the generated hammer beam laser light toward a first position on a part to provide an acoustic hammer pulse that induces surface movement of the part. An areal camera is arranged to produce an interferogram derived from reading surface movement of the part using the read-out beam directed to a second position on the part.

Abstract: This disclosure presents a process to determine characteristics of a subterranean formation proximate a borehole. Borehole material can be typically pumped from the borehole, though borehole material can be used within the borehole as well. Extracted material of interest can be collected from the borehole material and prepared for analyzation. Typically, the preparation can utilize various processes, for example, separation, filtering, moisture removal, pressure control, cleaning, and other preparation processes. The prepared extracted material can be placed in a photoacoustic device where measurements can be taken, such as a photoacoustic imager or a photoacoustic spectroscopy device. A photoacoustic analyzer can generate results utilizing the measurements, where the results of the extracted material can include one or more of fracture parameters, fracture plane parameters, permeability parameters, porosity parameters, and composition parameters. The results can be communicated to other systems and processes to be used as inputs.

Abstract: The invention relates to an ultrasonic subsurface imaging microscopy device, and a method of using such a device. The device comprises a probe, a laser beam source and a detector. The probe comprises a tip arranged at a first surface of the probe, and an illumination area arranged at a second surface of the probe. The laser beam source is configured for generating short pulses of laser light, and for directing said short pulses of laser light onto the illumination area of the probe for generating acoustic pulses in the probe. The probe is configured to guide said acoustic pulses towards an end of the tip which faces away from said probe. The detector is configured for time-resolved detection of acoustic vibrations in said tip and/or said probe in between subsequent acoustic pulses, in particular acoustic vibration from reflections of said generated acoustic pulses from subsurface structures in a sample.
