Abstract
A light grid for determining the distance between transmitter and receiver strips, includes a transmitter strip with one or more transmitter elements which emit radiation having a specific intensity, a receiver strip with one or more receiver elements which receive the radiation from an assigned transmitter element, and a control device for controlling the transmitter elements and/or the receiver elements and for evaluating the receiver elements. At least one of the transmitter elements and/or at least one of the receiver elements are configured as qualified transmitter and receiver elements. The control device is configured to control different combinations of intensities and amplification factors of the qualified transmitter and/or receiver elements and to ascertain a distance value as a function of the sum of the resulting intensity values of the controlled combinations.
