Patent number: 11885607Abstract: An interferometric distance-measurement device includes a multi-wavelength light source which provides a beam having at least three different wavelengths. An interferometer unit splits the beam into measuring and reference beams. The measuring beam propagates in the direction of a measuring reflector movable along a measuring axis and undergoes a back-reflection, and the reference beam propagates in the direction of a stationary reference reflector and undergoes a back-reflection. The back-reflected measuring and reference beams interfere with each other in an interference beam. A detection unit splits the interference beam such that several phase-shifted partial interference signals result for each wavelength. A signal processing unit determines absolute position information regarding the measuring reflector from the partial interference signals of different wavelengths and an additional coarse position signal.Type: GrantFiled: February 17, 2022Date of Patent: January 30, 2024Assignee: DR. JOHANNES HEIDENHAIN GMBHInventor: Herbert Huber-Lenk

Patent number: 7126414Abstract: An amplifier circuit (1) is disclosed, wherein with a view to reducing the leakage power of the amplifier circuit (1) a current path (6) is provided between a first output terminal (A1) and a second output terminal (A2) of the amplifier circuit, said current path being open in the case of an uptake of energy at the output of the amplifier circuit (1), so that the electrical energy taken up by the one output terminal (A1) can be drained away immediately via the other output terminal (A2). If no uptake of energy is taking place via the output of the amplifier circuit (1) but instead electrical energy is being released by the amplifier circuit (1), the current path (6) between the two output terminals (A1, A2) is closed.Type: GrantFiled: September 3, 2004Date of Patent: October 24, 2006Assignee: Infineon Technologies AGInventors: Herbert Huber, Tibor Olah

Patent number: 7092108Abstract: A method for position determination that includes generating first and second position-dependent scanning signals, transmitting the first and second position-dependent scanning signals from a scanning location via corresponding first and second scanning channels to corresponding first and second storage elements, storing corresponding first and second instantaneous values present at the first and second storage elements at corresponding first and second storage times. Forming a measured position value from the first stored instantaneous value and the second stored instantaneous value. A difference exists between corresponding first and second transit times of the first and second position-dependent scanning signals in the corresponding first and second scanning channels, the difference is compensated by individually delaying the first and second position-dependent scanning signals, so that the stored first and second instantaneous values have appeared at a common time at the scanning location.Type: GrantFiled: October 13, 2001Date of Patent: August 15, 2006Assignee: Dr. Johannes Heidenhain GmbHInventors: Jörg Drescher, Mathias Hausschmid, Herbert Huber-Lenk, Herbert Reiter, Johann Streitwieser, Wolfgang Holzapfel
