Abstract:
A photoelectric cell comprising:a photoreceptor circuit including a photoreceptor component having a photoreceptor area surface for receiving light; and a switch for assigning the photoreceptor circuit to a reflex operating mode or to a proximity operating mode, wherein: the photoreceptor surface comprises two juxtaposed photoreceptor areas each having differing microelectronic structures, the first photoreceptor area comprises a photodiode area and a first output for operating in the reflex operating mode, the second photoreceptor area comprises means for analog detection of position of a spot of light, a second output for operating in the proximity operating mode, and a third output, wherein the second output is a closed channel, and the third output is a remote channel of the second photoreceptor area for analog detection of position, said closed and remote channels for output of signals corresponding to relative distances to a target represented by a detected position of a spot of light, and the switch is for switching the first and second outputs to a processing circuit.
