Abstract: A system for the optical detection of objects includes a first source for generating light, microwaves, or ultrasound of a first wavelength. An object is illuminated by the light, the microwaves, or the ultrasound, wherein the illumination is distorted by the object. The system further includes at least one color light source for the generation of color light of a second wavelength, wherein the same object is illuminated by the color light of the color light source. The first wavelength is different from the second wavelength. Further, a sensor is provided for the detection of the object illuminated by the first source, and a second sensor is provided for the detection of the color light generated by the color light source, which is reflected by the object.

Abstract: A method for characterizing an object using distance measurement includes: determining elevation profiles using distance measurement, and evaluating the determined elevation profiles for a characterization of the object, the characterization includes a position and/or at least one object-specific parameter of the object.

Abstract: Method for characterizing an object by means of distance measurement, the method comprising the following steps: determining, in particular line-wise, elevation profiles using distance measurement, and evaluating the determined elevation profiles for a characterization of the object, wherein the characterization comprises the position and/or at least one object-specific parameter of the object.

Abstract: The present invention relates to an electrode device for gas discharge sources, a gas discharge source comprising such an electrode device and to a method of operating the gas discharge source. The electrode device comprises an electrode wheel (1) rotatable around a rotational axis (3) and a wiper unit (11) arranged to limit the thickness of a liquid material film applied to at least a portion of an outer circumferential surface (18) of the electrode wheel (1) during rotation of said electrode wheel (1). The wiper unit (11) is arranged and designed to form a gap (17) between the outer circumferential surface (18) and a wiping edge (19) of the wiper unit (11) and to inhibit or at least reduce a migration of liquid material from side surfaces to the outer circumferential surface (18) of the electrode wheel (1) during rotation.
