  • Publication number: 20220334400
    Abstract: A method for compensating beam angle variation of a beam bundle of laser beams with respective beam angles includes generating the beam bundle using a diffractive optical element, determining a beam angle value from a beam angle of at least one laser beam of a first subset of the laser beams, detecting a light pattern projected by a second subset of the laser beams, and evaluating the light pattern. The evaluation is performed taking into account the beam angle variation of the beam angles of the second subset of the laser beams on the basis of the determined beam angle value.

  • Patent number: 9603552
    Abstract: The invention relates to a measuring method for determining biometric data of human feet, comprising the following steps providing a reference object, which has at least one reference pattern, providing a freely moveable image recording device, automatically detecting the relative position and the alignment of the image recording device relative to the reference object using the at least one reference pattern, automatically recording of several images by the image recording device, wherein each individual image is only recorded, when the relative position and the alignment of the image recording device relative to the reference object corresponds to a triggering position predetermined for the respective image, determining biometric data of the at least one foot by means of the recorded images. Furthermore, the present invention relates to a measuring system as well as a pedestal for determining biometric data of human feet.

  • Patent number: 9325888
    Abstract: A method for measuring the height of an object, including projecting a light pattern having successive coded picture elements extending in a direction of a transversal axis onto the object by a light source. Each of the picture elements has at least one coding feature and the picture elements together define a code word. The picture element groups from a sequence of a predetermined number of successive picture elements each define individual partial code words, existing exactly once within the code word. Capturing the light pattern by a picture sensor arranged off-set to the light source. Determining the positions of the picture element groups and determining the height of the object the determined position of the picture element groups in comparison to a respective reference position.

  • Publication number: 20020093667
    Abstract: The present invention is concerned with monitoring moving operations, with an optical sensor (1) and an illuminating means (12). In order to provide a device for sensing or monitoring moving operations, in which an optimum lighting of the sensing area is ensured even when objects of greatly varying sizes are sensed, or respectively when the distance between the camera and the object to be sensed changes significantly from object to object, it is proposed according to the invention that a first deviation mirror (2, 2′) be arranged such that the light leaving the illumination means (12) is reflected.

  • Patent number: 6104427
    Abstract: A plurality of separate conveyings over each of which a single line camera is mounted and connected to a sensor processor, which itself is connected to a fast data network with a plurality of processing terminals. Because of the high resolution (up to 7000 picture elements per line) and a line scanning frequency of the order of up to 6000 hertz very large amounts of data are received, so in the preferred embodiment a high capacity data network is used, for example a 100 Mbit ethernet with a switching hub.
