United States Patent 8,210,045 (via Quarktet, Silver Spring)
Continuous laser generation of ultrasound
Abstract: A new invention for the laser-based generation of ultrasound is described. In conventional laser-based ultrasound, a pulse of light is incident on a solid. The light is converted to heat expanding the material near the surface. This thermoelastic expansion creates an acoustic wave in the material. Detection of the ultrasound allows the nondestructive inspection of the material. The rate of performing an ultrasound scan is inherently limited by the pulse rate of the laser. In this invention, a continuous wave (cw) high-power laser sweeps across the material, using thermoelastic expansion to create an ultrasound wavefront on the surface of and in the material. Detection of the ultrasound wavefront provides evidence of the strength of the material and the presence of defects. With Continuous Laser Generation of Ultrasound, material analysts will be able to perform ultrasound scans potentially hundreds of times faster than the current methods.

United States Patent 6,441,552 and 6,838,831
Apparatus and methods for generating persistent ionization plasmas
Abstract: A persistent ionization plasma generator is described that forms a plasma in a cavity that persists for a time after termination of the exciting RF electric field. The plasma generator includes a RF cavity that is in fluid communication with a source of ionizing gas. The RF cavity can be at substantially atmospheric pressure. An RF power source that generates an RF electric field is electromagetically coupled to the RF cavity. An ultraviolet light source is positioned in optical communication to the cavity. An antenna is positioned within the cavity adjacent to the ultraviolet light source. A chamber for confining the plasma can be positioned in the cavity around the antenna.

Non-thermal process for annealing crystalline materials
Abstract: Bulk crystalline materials are annealed by introducing into them mechanical energy of sufficient intensity to create a large amplitude sound wave. The mechanical energy may be introduced into the material, for example, by laser ablation. Where the bulk crystalline material is a doped semiconductor, the process also electrically activates the material.

Gas-coupled laser acoustic detection
Abstract: The investigation, development and application of a laser-based ultrasonic inspection system to the problems of evaluating polymer/graphite composite materials has been realized. The use of lasers to generate and detect ultrasonic waveforms in materials provides a means to detect material properties remotely. The study consisted of three main aspects: 1) A confocal Fabry-Perot (CFP) based system has been devolved which uses light reflected from the CFP interferometer to derive the ultrasonic signal. This allows higher frequency components of the detected waveforms to be discerned when compared to a CFP-based system using light transmitted through the CFP interferometer. 2) Thermoelastic and ablative laser generation of acoustic pulses in polymer/graphite composite materials has been investigated. Thermoelastic generation of ultrasound occurs when thermal energy deposited by a pulsed laser creates a localized expansion in the material. Ablative generation of ultrasound results from the creation of a plasma above the surface when the laser pulse surpasses an intensity threshold. 3) A novel technique, designated Gas-Coupled Laser Acoustic Detection (GCLAD), has been realized, in which the ultrasonic wave is detected optically after it has been transmitted from sample to air. This technique has the advantage of being independent of surface reflectivity and optical smoothness, and has comparable sensitivity to the CFP-based system.

United States Patent 6,859,564 (via Quarktet, Silver Spring)
Signal processing using the self-deconvolving data reconstruction algorithm
Abstract: A signal processing algorithm has been developed in which a filter function is extracted from degraded data through mathematical operations. The filter function can then be used to restore much of the degraded content of the data through use of any deconvolution algorithm. This process can be performed without prior knowledge of the detection system, a technique known as blind deconvolution. The extraction process, designated Self-deconvolving Data Reconstruction Algorithm (SeDDaRA), has been used successfully to restore digitized photographs, digitized acoustic waveforms, and other forms of data. The process is non-iterative, computationally efficient, and requires little user input. Implementation is straight-forward, allowing inclusion into all types of signal processing software and hardware. The novelty of the invention is the application of a power law and smoothing function to the degraded data in frequency space. Two methods for determining the value of the power law are discussed. The first method is by educated guess where the value is deemed a constant of frequency that ranges between zero and one. This approach requires no knowledge of the original data or the degradation and is quite effective. The second method compares the frequency spectrum of the degraded data to the spectrum of a signal with the desired frequency response. This approach produces a superior result, but requires additional processing.
