A frequency measurement system and method of a radio frequency (RF) signal. The frequency measurement system includes: a magnetic field source module, a light source module, an excitation module, a complementary metal-oxide-semiconductor (CMOS) camera, and a signal processing module; 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.
