Methods, devices and systems for measuring a measured variable |
| abstract |
One object of the invention is to improve methods, devices and systems for measuring a measured variable. For this purpose, a measured variable based on an NV center as a quantum sensor is measured in a measuring method. The NV center has several quantum states and can be optically excited into at least one excited state of the quantum states by means of an excitation light, depending on an occupation of one of the quantum states. The at least one excited state can decay at least with the emission of emission light from the NV center. In the measurement process, the NV center is irradiated with the excitation light, the excitation light having a periodic modulation and a respective occupation probability and / or a respective lifetime of the quantum states depending on the measured variable and the excitation light. A phase shift is determined between the emission light of the NV center and the modulation of the excitation light and, based on this, a measured value for the measured variable. |
