Patent number: 10551357Abstract: A method for high resolution photoacoustic imaging in scattering media using structured illumination may include illuminating a sample of an absorption object with structured illumination, including illuminating the sample with multiple different speckle patterns at different times. The method may also include detecting multiple photoacoustic signals generated by the absorption object in response to illumination with the different speckle patterns to generate multiple photoacoustic responses. The method may also include reconstructing an absorber distribution of the absorption object by exploiting joint sparsity of sound sources in the plurality of photoacoustic responses.Type: GrantFiled: September 28, 2017Date of Patent: February 4, 2020Assignees: The Regents of the University of Colorado, a body corporate, Research Center for Non Destructive Testing GmbH, University of InnsbruckInventors: Todd W. Murray, Peter Burgholzer, Markus Haltmeier

Patent number: 10401160Abstract: For a simple, fast, safe and reliable determination of the layer thickness of a bonding layer between two layers of a packaging, a laser ultrasonic method is provided, in which the transit time of the ultrasonic wave through the first and second packaging layers (2, 3) is determined in advance, and a maximum (M1, M2, Mn) in the measurement signal (S) is sought, and the point in time of occurrence of this maximum (M1, M2, Mn) is determined as the total transit time (T1, T2, Tn) of the ultrasonic wave, and the transit time of the ultrasonic wave through the first and second packaging layers (2, 3) is subtracted from the total transit time (T1, T2, Tn), and the thickness (d) of the bonding layer is deduced from the known ultrasonic speed (vS) in the bonding layer (5).Type: GrantFiled: March 12, 2014Date of Patent: September 3, 2019Assignees: CONSTANTIA TEICH GMBH, RESEARCH CENTER FOR NON DESTRUCTIVE TESTING GMBHInventors: Bernhard Reitinger, Saeid Zamiri, Clemens Gruensteidl, Juergen Roither, Martin Kornfeld, Alfred Wegenberger

Patent number: 9651364Abstract: A method for laser-optical detection of a surface movement of a sample (1) is specified, whereby a first laser reference beam (10) is superimposed with a first laser measurement beam (12) directed onto the sample (1) and reflected by the latter in a first photorefractive/electro-optical element (4). In addition, a second reference beam (11) identical to the first reference beam (10) is superimposed with a second measurement beam (13) identical to the first measurement beam (12) in a second photorefractive/electro-optical element (5). Mutually inverse voltages are applied to the two photorefractive/electro-optical elements (4, 5). The light emerging from the photorefractive/electro-optical elements (4, 5) is converted into electric signals which are subtracted from one another prior to the signal evaluation. Also specified is an arrangement for implementing said method.Type: GrantFiled: October 30, 2013Date of Patent: May 16, 2017Assignees: Fill Gesellschaft m.b.H., Research Center for Non Destructive Testing GmbHInventor: Bernhard Josef Reitinger

Patent number: 9649256Abstract: A method and a device for monitoring a property of a coating of a solid dosage form during a coating process forming the coating of the solid dosage form are provided. The device comprises a coating apparatus configured for forming the coating on the solid dosage form, and a monitoring apparatus configured for monitoring the property of the coating of the solid dosage form in process, wherein at least a part of the monitoring apparatus is located so as to have insight in an interior of the coating apparatus, the interior accommodating the solid dosage form to be coated and a precursor for forming the coating, and wherein the monitoring apparatus is configured for monitoring the property of the coating of the solid dosage form simultaneously with and during a coating process using low coherence interferometry.Type: GrantFiled: April 29, 2014Date of Patent: May 16, 2017Assignees: Research Center Pharmaceutical Engineering GmbH, Research Center for Non Destructive Testing GmbHInventors: Daniel Markl, Guenther Hannesschlaeger, Michael Leitner, Stephan Sacher, Daniel Koller, Johannes Khinast
