  • Publication number: 20220342071
    Abstract: The present invention relates to an FMCW-LiDAR distance measurement apparatus in which a light source, in particular a laser, generates a frequency modulated transmission light beam as a transmission signal having a predetermined frequency deviation and transmits said frequency modulated transmission light beam into a measurement zone; a light receiver receives light reflected by objects in the measurement zone as a reception signal; a mixer mixes at least a portion of the transmission signal with the reception signal and with an oscillator frequency to generate a mixed signal; and the oscillator frequency is adapted to a desired measurement zone to achieve a high measurement accuracy in the desired measurement zone.

  • Publication number: 20060231747
    Abstract: The invention relates to a method and to an apparatus for the processing of a received signal of an optoelectronic sensor, in particular of a light grid having a plurality of reception channels, with a comparison being carried out between the received signal and a signal delayed with respect to the received signal and the signal obtained by the comparison being supplied to a further processing.

  • Patent number: 6909081
    Abstract: An evaluation circuit for the processing of a received differential signal of an optoelectronic circuit, in particular of a light grid, is disclosed. The evaluation circuit has at least one differential amplifier for the amplification of the received signal. A clamping circuit, by which at least one output of the differential amplifier can be switched to a reference potential, is provided for the suppression of an offset of the differential amplifier. The invention further relates to a corresponding optoelectronic sensor and to a signal processing method.

  • Patent number: 6593563
    Abstract: A method is described for the operation of an opto-electronic sensor array, in which a plurality of sequential operating light pulses are emitted into a monitored region; the operating light pulses reflected from an object arranged in the monitored region are received by a spatially resolving receiver unit with a plurality of light sensitive sensors; the light intensity of the respectively received reflected operating light pulses is detected and stored in each case during an activation interval synchronously with the emission of the operating light pulses for each sensor; and after each activation interval, in sequential transmission steps, the light intensities stored for the sensors are transmitted to a parallel processor having a plurality of parallel signal inputs for the parallel signal processing, with the transmission in each case taking place for a plurality of sensors simultaneously in each transmission step. Furthermore, a sensor array for the carrying out of the method is described.
