摘要： A depth mapping device equipped with a 2D optical pattern projection mounted on a tool attached to a robot may be used to measure distance between the tool and an object. Depth data generated by the depth mapping device can be used to generate an augmented-reality image to provide real-time information about the object position, orientation, or other measurements to an operator performing a industrial robotic process. Images also may be generated with a camera located on the robot. Real-time depth information may be used to prevent collision. Fast depth information acquisition may be used to modify robot position for better processing. Real-time data acquisition plus fast processing may provide augmented-reality images to operators for better robot programming. Location data of the industrial process on the object may be used to improve analysis of the industrial process data.

摘要： A compact high average power mid infrared range laser for ultrasound inspection. The laser comprises one of a Nd:YAG or Yb:YAG laser pumped by a diode at 808 nm to produce a 1 micron output beam. The 1 micron output beam is directed to an optical parametric oscillator where the beam wavelength is converted to 1.94 microns and conveyed to a mid infrared emission head. The emission head comprises one of a Ho:YAG or Ho:YLG laser optically coupled with a second optical parametric oscillator. The second optical parametric oscillator forms a generation output beam for creating ultrasonic displacements on a target. The generation output beam wavelength ranges from about 3 to about 4 microns, and can be 3.2 microns.

摘要： A method of spectroscopic analysis of a material using a laser ultrasound system. The method includes measuring amplitude displacement of a target surface that has been excited with a generation laser. The amplitude displacements relate to the target's optical absorption properties. Amplitude displacements are generated over a range of laser wavelengths to obtain an optical absorption signature useful to identify the target material characteristics.

摘要： A method of ultrasonic testing comprising conditioning a radiation wave from a laser source by efficiently converting the radiation wave's wavelength to a mid-IR wavelength for enhanced ultrasonic testing of a composite. The method includes passing the radiation wave through a first optical frequency converter where the radiation wave is converted into a signal wave and an idler wave, where the idler wave is at a mid-IR wavelength. The method further includes directing the signal and idler waves to a second optical frequency converter where the signal wave wavelength is converted to a mid-IR wavelength which combines with the idler wave to form a generation wave. The generation wave is directed at a composite surface to be tested.

摘要： A method for inspecting a sandwich structure may comprise determining a reference frequency, directing first and second laser beams onto the structure, collecting reflected light, processing it using an interferometer, acquiring a time-dependent signal for a predetermined duration greater than a period corresponding to the reference frequency, processing the time-dependent signal to produce a frequency-dependent signal, and comparing characteristics of the processed frequency-dependent signal to the reference frequency. A laser-ultrasonic apparatus configured to inspect sandwich structures may comprise first and second laser beams configured to generate acoustic energy in and illuminate a sandwich structure, respectively, an interferometer configured to receive reflected light and generate a time-dependent signal, detection electronics configured to process the time-dependent signal to produce a time-dependent electrical signal, and one or more processing units configured to convert the time-dependent electrical signal into a frequency-dependent signal and to compare characteristics thereof to characteristics of a reference frequency-dependent signal.
