摘要： A sensor includes two magnetic sensors detecting a magnetic field around an object, and outputting at least one of a magnetic field signal and a temperature signal, an optical system emitting the excitation light to the two magnetic sensors, and a processor calculating a difference between a magnetic fields corresponding to the magnetic field signal detected by the two magnetic sensors, wherein each of the magnetic sensors includes an element disposed around the object and having color centers, an antenna radiating a microwave magnetic field to the element, an optical sensor detecting an intensity of a fluorescence generated by the element, and outputting an intensity signal, and a controller calculating at least one of a magnetic field and temperature around the measurement object, and output at least one of a magnetic field signal indicating the calculated magnetic field and a temperature signal indicating the calculated temperature to the processor.
