Patent number: 11413007Abstract: Methods and systems for measuring one or more properties of a soft material employ air transmitted ultrasound that is reflected from the soft material to generate a mechanical wave in the soft material. A method of measuring one or more properties of a soft material includes transmitting ultrasound through air to an interface boundary between the soft material and air. Force is applied to the soft material by reflecting the ultrasound from the soft material. A mechanical wave is generated in the soft material as a result of the force applied to the soft material. Propagation of the mechanical wave in the soft material is measured with an imaging system. One or more properties of the soft material is determined based on the measured propagation of the mechanical wave in the soft material.Type: GrantFiled: May 26, 2017Date of Patent: August 16, 2022Assignee: University of WashingtonInventors: Lukasz Ambrozinski, Matthew O'Donnell, Ivan Pelivanov, Soon Joon Yoon, David Li, Shaozhen Song, Ruikang K.

Patent number: 10955335Abstract: A non-contact photoacoustic spectrophotometry system is configured to measure an absorption spectrum of a material. The system includes a modulated light source such as tunable pulsed laser that generates laser pulses to produce photoacoustic signals in the material. A non-contact detector monitors the surface of the container for the material. The detector includes a second light source, such as a continuous wave laser, focused on the surface of the container, and transmits reflected light to an interferometer, for example, a Sagnac interferometer. The interferometer produces an interference signal from the received light that is proportional to the acoustic pressure, which is transmitted to a computer to calculate an absorption coefficient. Using a plurality of wavelengths from the tunable pulsed laser, an absorption spectrum may be generated.Type: GrantFiled: March 28, 2019Date of Patent: March 23, 2021Assignee: University of WashingtonInventors: Ivan Pelivanov, Matthew O'Donnell, Elena Petrova, Soon Joon Yoon

Patent number: 10888304Abstract: Methods and system for producing combined photoacoustic/ultrasonic image frames use a low-power narrow beam laser to direct sequential pulses along a path overlying an internal region of interest. Photoacoustic responses are received and used to generate sub-frames. Between each of the laser pulses a plurality of ultrasound pulse-echo beams are sequentially emitted towards the region of interest, and the reflections are received and used to generate ultrasound sub-frames. The photoacoustic sub-frames are combined to produce a photoacoustic frame, and the ultrasound sub-frames are combined to produce an ultrasound frame. The photoacoustic and ultrasound frames are combined to produce an image frame. The method and system are suitable for producing real-time, high-contrast video.Type: GrantFiled: May 11, 2015Date of Patent: January 12, 2021Assignee: University of WashingtonInventors: Matthew O'Donnell, Thu-Mai Nguyen, Chen-Wei Wei, Jinjun Xia, Ivan Pelivanov, Soon Joon Yoon

Patent number: 10323925Abstract: A compact and portable apparatus for measuring properties of objects utilizing a fiber optic Sagnac interferometer is enabled. The fiber optic Sagnac interferometer may be a double differential Sagnac interferometer. The interferometer core may be implemented with fiber optic components including polarization maintaining optical fiber, and by utilizing an auto-balanced avalanche photodetector. An optical switch may be incorporated to maintain relatively low average probe signal power while allowing optimal peak probe signal power. The compact and portable apparatus may be configured to measure ultrasonic vibrations, a displacement of an object surface in response to ultrasonic vibrations, and/or a vibration speed of the object surface. A wideband light source may be amplified and stabilized. A sensor head of the interferometer may incorporate a collimator adjustable to block a central portion of the projected probe beam thereby at least in part enabling in-plane and out-of-plane measurements.Type: GrantFiled: October 24, 2016Date of Patent: June 18, 2019Assignee: UNIVERSITY OF WASHINGTONInventors: Ivan Pelivanov, Matthew O'Donnell
