Optoelectronic sensor element

The apparatus has an LED light source (10) and a polarizer (12) for rotating relative to one another in dependence on a rotary angle. A receiver measures light intensity reflected by the polarizer to generate a signal dependent on an angle of rotation. The receiver is configured as an optoelectronic...

Beschreibung
Zusammenfassung:	The apparatus has an LED light source (10) and a polarizer (12) for rotating relative to one another in dependence on a rotary angle. A receiver measures light intensity reflected by the polarizer to generate a signal dependent on an angle of rotation. The receiver is configured as an optoelectronic sensor element (20) including a reception element i.e. photodiode, in front of which a polarizing structure i.e. wire grid polarizer, is arranged. The structure includes a contact connection connected to a defined potential by a wire, where the structure is configured as a screen of the element. Die Erfindung betrifft ein optoelektronisches Sensorelement (20) mit wenigstens einem Empfangselement (22, 22a, 22b, 22c, 22d), vor welchem eine polarisierende Struktur (24, 24a, 24b, 24c, 24d) angeordnet ist, welche aus einem elektrisch leitfähigen Material gefertigt ist, wobei die polarisierende Struktur (24, 24a, 24b, 24c, 24d) einen Kontaktanschluss (26) zum Anlegen eines definierten Potentials aufweist und dass die polarisierende Struktur (24, 24a, 24b, 24c, 24d) als Abschirmung des Sensorelements (20) ausgebildet ist.
