Latest Patents
Kruger's latest patents include a method and apparatus for highly accurate distance measurement. This invention involves determining the profile of a surface using contactless distance measurement. A light pencil, which has been scattered and reflected from the surface, is split into two light pencils with substantially the same distribution of intensities. The ratio of the intensities of these partial pencils is dependent on the principal beam direction of the scattered light. By detecting at least one of the partial pencils with a photodetector, the resulting signal is evaluated as an accurate measure of surface profile or roughness. This method significantly reduces noise from interference phenomena, enhancing the reliability of the evaluated signals.
Another patent by Kruger focuses on the interferometric detection of surface displacements of solids, particularly in test materials excited with ultrasonic waves. In this invention, an illumination laser radiates the test material surface, and a portion of the reflected light is brought into a state of interference after passing through differing optical path lengths. The interference is identified by an installed detector. This invention improves upon prior art by employing a joint illumination laser to operate several interferometers equipped with waveguides, thus enhancing sensitivity and efficiency in detecting ultrasonic events.
