Abstract
Photoreceptor circuit provided with a component, the photoreceptor surface comprising a first area able to operate in reflex mode and a second area with analog detection of position able to operate in proximity mode. The first area Z1 is a photodiode area with an output Al and the second area Z2 is a PSD type area provided with a close output A2 and a remote output A3, wherein a switch I1 connects either the A1 output in reflex mode or output A2 in proximity mode, to a processing circuit 12.
Claims3
A photoelectric cell including an optoelectronic receptor circuit provided with a photoreceptor component, the photoreceptor area of which is able to receive a spot of light characterized by the fact that:
- the photoreceptor surface of the component (11) has two juxtaposed photoreceptor areas (Z1, Z2), wherein these areas differ by their microelectronic nature,
- the cell has means (I1) for assigning the photoreceptor circuit to a reflex operating mode or to a proximity operating mode,
- the first photoreceptor area (Z1) is provided with a first output (A1), enabled in the reflex operating mode,
- the second area (Z2) is provided with analog detection of position of the spot of light and is provided with a second output (A2), enabled in the proximity operating mode.
