Abstract

The present disclosure includes a method for correcting a primary measurement signal detected by an optical detector. The method includes: emitting a first light signal from a light source to an active sensor layer such that the active sensor layer is stimulated and emits a second light signal, which is detected by an optical detector; determining the primary measurement signal of a primary measurement parameter based on the second light signal and/or the first light signal; determining a secondary measurement signal of a secondary measurement parameter that is different from the primary measurement parameter based on the first light signal or the second light signal; comparing the determined secondary measurement signal with a first limit value; and correcting the primary measurement signal when the secondary measurement signal exceeds the first limit value, wherein correcting the primary measurement signal comprises smoothing the primary measurement signal by filtering.
