Abstract
A sensor system includes a quantum dot including one or more paramagnetic centers. It comprises a control and evaluation device including a pump radiation source, a radiation receiver and which irradiates the quantum dot depending on a transmission signal. The quantum dot emits fluorescence radiation upon irradiation with the pump radiation, which depends on the magnetic flux density and/or on another physical parameter. The control and evaluation device generates an output signal including a measured value as a function of the fluorescence radiation. The control and evaluation device compensatingly readjusts the sensitivity of the quantum dot for the magnetic flux density and/or the other physical parameter by means of one or more compensation coils.
