Method for correcting a primary measurement signal detected by an optical sensor

A method for correcting a primary measurement signal detected by an optical detector, the method comprising:

• providing an optical measuring device including a light source, an active sensor layer, an optical detector and a controller, wherein the controller is in communication with the light source and the optical detector;
• emitting a first light signal from the light source, the first light signal directed toward the active sensor layer such that the active sensor layer is stimulated and emits a second light signal, which is directed toward the optical detector;
• detecting the second light signal emitted by the active sensor layer using the optical detector;
• determining the primary measurement signal of a primary measurement parameter using the controller based on the first light signal or based on the first light signal and second light signal;
• determining a secondary measurement signal of a secondary measurement parameter using the controller based on the first light signal or the second light signal, wherein secondary measurement parameter different from the primary measurement parameter;
• comparing the determined secondary measurement signal with a first limit value using the controller;
• correcting the primary measurement signal using the controller when the secondary measurement signal exceeds the first limit value, wherein correcting the primary measurement signal comprises filtering the primary measurement signal such that the primary measurement signal is smoothed.
