Publication number: 20220413098Abstract: The invention relates to a system and a method for simultaneous range and velocity measurement in an FMCW LiDAR system. A first light source (16) produces first light having a first frequency that varies according to a first chirp rate. A second light source (18) produces second light having a second frequency that is constant or that varies according to a second chirp rate being different from the first chirp rate. Measuring light obtained by combining the first and second light therefore has two different frequency components during a measurement interval. A splitter (22) separates the measuring light into reference light and output light, and a scanning unit (28) directs the output light towards an object (12) and receives input light that is obtained by reflection of the output light at the object (12). A detector (32) detects a superposition of the reference light and the input light.Type: ApplicationFiled: June 25, 2021Publication date: December 29, 2022Inventors: Frank HÖLLER, Peter WESTPHAL

Publication number: 20210190951Abstract: A method for operating a LIDAR system with at least one spectrally tunable light source emitting a light beam having a temporally varying frequency and a transparent protective shield, arranged in a light path of the light beam, protecting the LIDAR system against environmental pollution includes determining distance values of an object based on beat frequencies of beat signals resulting from a superposition of partial signals obtained from partial reflection of the light beam at the object with reference signals not reflected at the object. Each distance value is determined from a peak in a signal spectrum obtained on the basis of a Fourier transformation of the beat signal. A degree of soiling of the protective shield is diagnosed by analyzing the signal spectrum in a predefined analysis frequency range. An upper limit frequency bounding said analysis frequency range is based on a distance of the protective shield.Type: ApplicationFiled: December 17, 2020Publication date: June 24, 2021Inventors: Frank HÖLLER, Thomas WOLLWEBER, Jan HORN, Peter WESTPHAL

Publication number: 20210191110Abstract: A device for two-dimensionally scanning beam deflection of a light beam has spectrally tunable light source that emits a light beam having a time-varying wavelength. The device further comprises a first optical component that produces a first beam deflection. The first beam deflection causes the light beam to be deflected wavelength-dependently in a first direction. A second optical component produces a second beam deflection which causes the light beam to be deflected in a second direction different to the first direction. The second optical component comprises a prism pair comprising two prisms that are rotatably arranged successively in a beam path of the light beam. The two prisms are configured to perform continuous counter-rotational movements.Type: ApplicationFiled: December 22, 2020Publication date: June 24, 2021Inventors: Frank HÖLLER, Kerstin WINKLER, Felix KOCH

Publication number: 20210026017Abstract: An apparatus for ascertaining a distance to an object has a light source that emits an optical signal having a time-varying frequency. An evaluation device ascertains a distance to the object based on a measurement signal that originated from the optical signal and was reflected at the object and, and on a reference signal that was not reflected at the object. A dispersive element produces a frequency-selective angle distribution of the measurement signal that has a plurality of partial signals which are steered to the object at mutually different angles.Type: ApplicationFiled: September 2, 2020Publication date: January 28, 2021Inventors: Vladimir DAVYDENKO, Frank HÖLLER, Andy ZOTT
