Abstract
A light sensing device having background suppression includes: a light transmitter, a light receiver, an evaluation unit for determining the spacing between the light sensing device and an object in a detection zone of the light sensing device, and a setting element for setting a sensing depth within which an object should be detected. A critical spacing region is defined between a set sensing depth and a background in dependence on the set sensing depth. A signal output outputs a signal if an object is detected within the set sensing depth and a display unit displays whether an object is present within the sensing depth. The set sensing depth can be displayed in relation to a maximum sensing depth of the light sensing device in a first display region and a second display region indicates if an object is located in the critical spacing region.
