Abstract: A sensor for automatic doors or gates that works based on a pulse-echo evaluation comprises a rotating mirror having at least three different emitting mirror facets, where the rotational axis lies normal to a reference plane, and at least one light-pulse generation unit generating infrared pulses having a certain beam width. The pulses are sent along two different emitting optical paths, each having at least one optical component, where the emitted pulses can be reflected by the mirror facets, and the emitting optical path defines an incident pulse direction of the emitted pulses. The reflected pulses establish a scanning field, where each of the reflected pulse directions defines a reflected beam projection on the reference plane (R), where the angle (IA) between the projections of the incident beams, namely the projection of the incident pulse directions onto the reference plane, is between 30° and 160°. The rotational axis (A) lies on the bisectrix (BS) of the beam projections between the intersection plane and the optical component closest to the rotating mirror along the optical path. The rotating mirror and its rotational axis (A) are set such that each reflected beam projection from both incident optical paths has an innermost reflected pulse (IB) at least parallel to the bisectrix (BS) or even crossing the bisectrix (BS) on the side of the scanning field. The scanning field is delimited by two outermost reflected pulses (OBa, OBb), where the scanning field therebetween has an angular range of more than 150°. The rotating mirror has the same amount of receiving mirror facets as the emitting mirror facets. The reflected pulse is echoed back by an object in the scanning field where the echoed pulse is reflected by the receiving mirror facet and then received by a receiver such that it is distinguishable over which emitting optical path the emitted pulse of the echoed pulse was sent.

According to the invention after a predefined timespan (TL) of no detection within said sensor safety areas of said sensors, the monitoring system (11) is set to a “restricted mode” in which at least one sensor safety area is set to a restricted area, where the safety signal is then provided upon detection of an object within the restricted area, where further, once a detection in the restricted area occurs, the monitoring system is set back to an unrestricted “normal” mode.

Abstract: Laser scanner monitors region in front of an opening. Monitoring region is delimited by a frame, in front of which an edge region is located. Propagation time sensing means determines position of an object in the monitoring region by a propagation time measurement of laser pulse, an evaluation unit being provided, by means of which first object information is produced, whether an object was sensed by the propagation time measurement. An intensity sensing means evaluating received laser pulse with respect to the intensity thereof and the sensed intensity is compared with a reference intensity stored in a memory unit. Second object information being provided in the event of deviation beyond a certain threshold value, whether an object is located in the hazard edge region on the basis of the intensity deviation. A “safety signal” generated by the evaluation unit if first or second object information is positive.
