Publication number: 20240167870Abstract: The present application discloses an apparatus and method configured to measure characteristics of high power beams of laser energy used in material processing. In one embodiment, the apparatus includes a housing having a first compartment and a second compartment separated from each other to reduce the transfer of thermal energy between them. Optical modules having optical sensors configured to measure characteristics of the high power beam are mounted in the first compartment. A removable and replaceable beam dump configured to absorb most of the high power beam is positioned in the second compartment. The removability/replaceability of the beam dump enables operation of the apparatus without active cooling of the beam dump assembly, simplifying the apparatus and protecting the optical sensors in the first compartment.Type: ApplicationFiled: January 11, 2024Publication date: May 23, 2024Applicant: OPHIR OPTRONICS SOLUTIONS LTD.Inventors: Oleg ZINOVIEV, Karol SANILEVICI, Alexandr SUPERFIN

In one embodiment, the apparatus includes a housing having a first compartment and a second compartment separated from each other to reduce the transfer of thermal energy between them. Optical modules having optical sensors configured to measure characteristics of the high power beam are mounted in the first compartment. An optical window operative to allow a significant portion of the beam to propagate therethrough is mounted in an intermediate housing member separating the first and second compartments. A removable and replaceable beam dump configured to absorb most of the high power beam is positioned in the second compartment. The removability/replaceability of the beam dump enables operation of the apparatus without active cooling of the beam dump assembly, simplifying the apparatus and protecting the optical sensors in the first compartment.Type: GrantFiled: January 14, 2022Date of Patent: January 16, 2024Assignee: OPHIR OPTRONICS SOLUTIONS, LTD.Inventors: Oleg Zinoviev, Karol Sanilevici, Alexandr Superfin

Publication number: 20120236135Abstract: Methods and apparatus for registration of digital images of a plurality of dental surfaces of a patient. Multiple dental surfaces are separately scanned and digitized, where each of the surfaces has at least one marked area. All marked areas are optically acquired, creating digitized images of the plurality of dental surfaces, which are then registered in a common reference frame on the basis of a specified marked areas. In some cases, a first dental surface is disposed on an upper dental arch and a second dental surface is disposed on a lower dental arch. Marked contact areas may be indicative of local occlusion pressure.Type: ApplicationFiled: March 13, 2012Publication date: September 20, 2012Applicant: OPTIMET, OPTICAL METROLOGY LTD.Inventors: Yitzhak Daniel, Karol Sanilevici, Michael Doherty, Alex Entelis

Patent number: 7728989Abstract: Methods for digitizing complex surfaces of dental objects such as impressions of dental surfaces and shapes. While an impression mold is being scanned by translation along a known trajectory, typically in a plane, the line of sight of a distance probe is directed toward successive positions on the surface of the impression mold, such as by a periodic series of reflecting surfaces characterized by normal vectors at distinct non-orthogonal angles with respect to their axis of symmetry. One or more reference objects are scanned using the same translation and mirror positioning systems. Gathered coordinate data are processed to apply angular corrections and combined to form a single distortion-corrected image of the impression mold. An apparatus and methods are provided for measuring both sides of a dental object separately, and then registering the two sides relative to each other in a digital representation of the object.Type: GrantFiled: July 27, 2007Date of Patent: June 1, 2010Assignee: Optimet, Optical Metrology Ltd.Inventors: Michael Doherty, Yitzhak Daniel, Eli Zeitlin, Karol Sanilevici, Gabriel Y.

Patent number: 7375827Abstract: An apparatus and method for digitization of surfaces of complex objects such as dental surfaces or plastic parts. While an object is being scanned by translation along a known trajectory, typically in a plane, the line of sight of a distance probe is bent toward an object by a periodic series of reflecting surfaces characterized by normal vectors at distinct non-orthogonal angles with respect to their axis of symmetry. One or more reference objects are scanned using the same translation and mirror positioning systems. Gathered coordinate data are processed to apply angular corrections and combined to form a single distortion-corrected image.Type: GrantFiled: January 24, 2005Date of Patent: May 20, 2008Assignee: Optimet, Optical Metrology Ltd.Inventors: Karol Sanilevici, Gregory Agronik
