摘要： The present invention provides an optical filter assembly that reduces the phase and amplitude noise of a detection laser used to detect ultrasonic displacements. The filtered detection laser is directed to the surface of a remote target. Ultrasonic displacements at the surface scatter the filtered detection laser. Collection optics then gather phase modulated light scattered by the surface and direct the phase modulated light to an optical processor to produce a signal representative of the ultrasonic displacements with an improved SNR. Additional processors may determine the structure of the remote target.

These defects may include flaws, delaminations, voids, fractures, fissures, or cracks, among others. The system utilizes an ultrasound measurement system, a signal analyzer and an expected result. The signal analyzer compares the signal from the measurement system to the expected result. The analysis may detect a defect or measure an attribute of the manufactured object. Further, the analysis may be displayed or represented. In addition, the expected result may be generated from a model such as a wave propagation model. One embodiment of the invention is a laser ultrasound detection system in which a laser is used to generate an ultrasonic signal. The signal analyzer compares the measured ultrasonic signal to an expected result. This expected result is generated from a wave propagation model. The analysis is then displayed on a monitor.

摘要： The present invention provides a method to detect and generate ultrasonic displacements at a remote target for ultrasonic inspection. This method involves generating an ultrasonic wave at a first location on an upper surface of the remote target. This ultrasonic wave is reflected from interior surfaces within the remote target wherein the reflected ultrasonic wave produces ultrasonic displacement at a second location on the upper surface of the remote target. A detection laser beam is generated and directed to the second location on the upper surface of the remote target. Here, the detection laser beam is scattered by the ultrasonic displacements to produce phase-modulated light. This phase-modulated light is collected and processed to obtain data representative of the ultrasonic surface displacements. Further, these ultrasonic displacements, when processed, will yield inspection information associated with the interior of the remote target.

摘要： The present invention provides a compact optical probe assembly that measures ultrasound in materials. The probe uses angle-terminated optical fiber to direct illumination laser light at the surface of a remote target. Ultrasonic displacements at the surface scatter the illumination laser light. Angle-terminated optical fibers collect phase modulated light and direct the phase modulated light to an optical processor to produce a signal representative of the ultrasonic surface displacements. The probe may also incorporate angle-terminated optical fibers to direct generation laser light to the surface of a remote target to generate ultrasonic surface displacements. Optional shared beam forming element(s) may optically act on the illumination laser and collected phase modulated light.
