Optical sensor device

An optical sensor device comprises a first and a second optical sensor arrangement. In the first optical sensor arrangement at least one optical sensor structure measures the incidence angle of incoming light that is approximately on the main beam axis of a light source. The second optical sensor ar...

Zusammenfassung:An optical sensor device comprises a first and a second optical sensor arrangement. In the first optical sensor arrangement at least one optical sensor structure measures the incidence angle of incoming light that is approximately on the main beam axis of a light source. The second optical sensor arrangement comprises at least one optical sensor structure with at least one optical sensor, at least two metal layers and opaque walls optically isolating the optical sensor. An evaluation circuit provides an output signal of the second optical sensor arrangement under the condition that the incidence angle measured by the first optical sensor arrangement lies within a set interval.
