Spectrum of the amplitude-modulated wave is observed by a radio frequency spectrum analyzer and amplitude values of every spectrum are recorded at the upper sideband or lower sideband.
In the paper. the interference intensity of signal laser beam and the reference one is carried out in detail on a heterodyne laser probe with amplitudemodulated laser source.
