Patent number: 10628927Abstract: A computer-aided image correction method for images with at least spatially partially coherent light requiring only a phase-modulated image as input. It does not reconstruct the phases on the image sensor, but rather assumes that they should ideally all be the same. With this assumption, the invention formulates a constraint and an update rule. The result of the iteration is an amplitude distribution of the lightwave field, which could have been measured directly if aberrations in the form of wavefront distortions had not contributed to the actual image acquisition. Further, a device that can, using the image correction method, be used as an adaptive optic for imaging instruments.Type: GrantFiled: June 13, 2017Date of Patent: April 21, 2020Assignee: Christian-Albrechts-Universitaet zu KielInventor: Claudius Zelenka

Patent number: 10613159Abstract: A magnetic field measuring method using a magnetoelectric composite element as an oscillator, in which a time-dependent measurement magnetic field acts on the magnetostrictive phase of the composite element, and an electrical measurement voltage is tapped off across the piezoelectric phase of the composite element and is used to infer the measurement magnetic field.

When an electrical voltage is applied, the dielectric phase exhibits a change in length, the magnitude of which depends in a non-linear manner on the magnitude of the voltage, and a temporally periodic electrical modulation voltage is applied to the dielectric phase.Type: GrantFiled: May 31, 2016Date of Patent: April 7, 2020Assignee: Christian-Albrechts-Universitaet zu KielInventors: Patrick Hayes, Andre Piorra, Reinhard Knoechel, Eckhard Quandt
