Method for operating light curtain arrangement and light curtain arrangement

A method for operating a light curtain arrangement for monitoring a safety area, the light curtain arrangement comprising a plurality of first light emitter elements placed at an emitter side of the safety area, wherein the light emitter elements are arranged in a fixed geometric pattern, and a plurality of second light receiver elements placed at a receiver side of the safety area, wherein the light receiver elements are arranged in a fixed geometric pattern, and wherein the emitter side and the receiver side are separated by a predetermined distance, the method comprising the steps of:

• assigning a plurality of dedicated light emitter elements among the plurality of first of light emitter elements to a respective one light receiver element among the plurality of second light receiver elements, wherein the assigned light emitter elements form an array;
• and
• activating the dedicated light emitter elements of a respective array to contemporaneously emit light, and at the same time, receiving the emitted light from the activated light emitter elements by the respective light receiver element.
