A background suppression device includes emitting means emitting a light beam emitted in a set direction and optoelectronic receiving means of a light beam reflected by an object providing a first and a second signal, and processing means which, in the detecting condition of the device, receives the first and second signal and provides an output information signal, in function of the first and second signal, indicating the presence or the absence of the object within an interval of set distances. The processing means stores, in a calibrating condition, the first and second signal and provides the output information signal in function of the first and/or of the second signal in the detecting condition and of the first and/or second signal in the calibrating condition. In the calibrating condition the object is absent and accordingly the first and second signal in the calibrating condition store the background.
