Abstract: An optical scanner comprises a light transmitter for transmitting a light beam; a beam deflection unit that is configured to deflect the transmitted light beam in a periodically varying manner with a predefined period duration in order to scan a detection zone; a light receiver for receiving reflected light; and an electronic control device for controlling the beam deflection unit. The electronic control device is configured to automatically increase or decrease the period duration by a difference amount with respect to a nominal value before or during the operation of the optical scanner in order to counteract crosstalk between the optical scanner and a further optical scanner.

Abstract: A method of a contactless safeguarding of a machine is provided in which a plurality of protected fields configured in the environment of the machine are monitored for protected field intrusions by at least one optoelectronic sensor and, on a protected field intrusion, a safe output signal is generated at a safe output associated with the protected field. The protected fields are configured such that a vehicle approaching the machine results in a different sequence of protected field intrusions than a person approaching the machine and the sequence of protected field intrusions is evaluated to distinguish the vehicle and the person from one another. Three-dimensional protected fields are monitored that have at least two layers, having a lower layer and an upper layer arranged thereabove; and in that the configuration of the protected fields in the lower layer differs from the configuration of the protected fields in the upper layer.
