CPC G01R 29/0885 (2013.01) [G01R 29/0871 (2013.01)] | 20 Claims |
1. A frequency measurement system of a radio frequency (RF) signal, comprising:
a magnetic field source module, a light source module, an excitation module, a complementary metal-oxide-semiconductor (CMOS) camera, and a signal processing module, wherein
the magnetic field source module is configured to generate a magnetic field;
the excitation module is disposed in the magnetic field; the excitation module is disposed on an output light path of the light source module; the CMOS camera is disposed on an output light path of the excitation module; and the CMOS camera is connected to the signal processing module;
the light source module is configured to emit a laser;
the CMOS camera is configured to capture an excitation image when the laser enters the excitation module to which a to-be-tested RF signal is applied; and
the signal processing module is configured to determine a frequency of the to-be-tested RF signal according to the excitation image.
