摘要： The invention relates to an optoelectronic component for the positional determination of an incident light beam in a longitudinal axis direction, having flat sides, longitudinal sides and two oppositely disposed end sides, having a low ohmic first contact layer at a first flat side for a first electric contact (cathode) and having at least two low ohmic second contact layers along the end sides for second contacts (anodes). The invention additionally relates to a light sensor having such a component. To provide an improved optoelectronic component for the positional determination of an incident light beam as well as to provide an improved light sensor having such an optoelectronic component, it is proposed that at least one of the second contact layers not only extends along the end side but also over part sections along a second and third long side longitudinal side.

摘要： An optoelectronic sensor includes at least one light transmitter for the transmission of light signals into a monitored zone and at least one light receiver for the reception of transmitted light signals. In this respect, the received light signals are converted into electrical received signals in the light receiver. The light signals transmitted by the light transmitter are each generated on the basis of an output signal spread in accordance with a frequency spreading technique (spread spectrum) and provided with an offset applied for the generation of a unipolar signal. The electrical received signals can be supplied to a high-pass filter in the light receiver. Means for interference suppression are provided to automatically measure repeatedly or continuously respective then current interference; to analyze it in the time domain and/or in the frequency domain; and to compensate it at least substantially in dependence on the respective result of the interference analyses.
