摘要： A pulse detection laser is provided. The pulse detection laser includes a single frequency oscillator, a continuous pre-amplifier, and a pulsed amplifier. The single frequency oscillator generates a seed laser beam and is optically coupled to the continuous preamplifier. The continuous pre-amplifier amplifies the seed laser to produce an intermediate power laser beam. A pulsed amplifier optically coupled to the continuous pre-amplifier receives the intermediate power laser beam and amplifies the intermediate power laser beam to produce a pulse detection laser beam. One task of this pulse detection laser is to illuminate ultrasonic displacements. Light from the laser is scattered, collected, and analyzed with an interferometer to demodulate the ultrasonic displacements caused by the return echoes of the ultrasound at the surface of the part.

摘要： Embodiments of the present invention relate to a laser system and method for the optical generation of ultrasound at a remote target. This involves generating a pump laser beam with a diode-pumped fiber laser. The diode pumped fiber laser is fiber-coupled with an optical fiber, either passive or diode pumped, to a generation laser head. The generation laser head generates a generation laser beam from the pump laser beam and directs the generation laser beam to the surface of the remote target. The interaction between generation laser beam and the surface of the remote target results in ultrasonic displacements at the remote target. These ultrasonic displacements may be sampled in order to assess and inspect the remote target.

摘要： Containerized systems are provided. In one embodiment, a containerized system includes a moveable three-dimensional container, a first generator, a second generator, and a scanner. The first generator is located within the container, and the second generator is located outside of the container. The scanner is mechanically supported by the container and transmits waves received from the first and the second generators. The containerized system optionally includes one or more rails connected to the outside of the container, and the scanner moves along the one or more rails. The containerized system may also include a multi-axes arm that positions the scanner and that is mechanically supported by the container. Furthermore, the containerized system may include an interferometer, an electronics rack, and/or an air conditioning unit.
