Method for processing the receiver signal of an optoelectronic sensor, especially a light gate, whereby the receiver signal is supplied to a detection circuit with different time delays. The receiver circuit subtracts the two signals with different time delays from each other and evaluates the difference signal to determine if it exceeds or falls below predetermined thresholds. A detection signal is generated accordingly. The invention also relates to a corresponding analysis circuit for processing the received signal of an optoelectronic sensor. |
