Method for determining, measuring and/or monitoring properties of a sensor system

A sensor system, comprising:

• a control and evaluation unit configured to determine and/or measure and/or monitor properties of a sensor system, the control and evaluation unit being configured to perform the following:
• in a first step, a controlled change of at least one system parameter of the sensor system taking place in such a way that prior to the controlled change, the system parameter includes a first value and assumes at least one further value as a result of the controlled change;
• in a second step, determining at least one characteristic variable of the sensor system and/or a change of the at least one characteristic variable of the sensor system, for the at least one further value of the system parameter;
• in a third step, determining and/or measuring and/or monitoring of properties of the sensor system based on the at least one further value of the system parameter and based on the at least one characteristic variable determined in the second step and/or based on the change of the at least one characteristic variable.
