The invention discloses a method for measuring Bohr resonance phase difference and modifying data through continuous photographing or camera shooting, relates to the field of physical experiment parameter measurement, and discloses an experiment method which takes the place of a method for measuring phase difference by stroboflash. According to the technical scheme, a scale ruler is suspended between a balance wheel and a rocker, wherein the scale ruler takes the shape of an arc with angle scales; a balance wheel pointer is fixed on the balance wheel; when Bohr resonance forced vibration is in a stable state, the relationship between the balance wheel and the rocker in Bohr resonance forced vibration is recorded through continuous photographing or camera shooting; the time difference delta T generated when the balance wheel pointer and a rocker pointer point to one same scale on the scale ruler, and the swinging period T are confirmed through a computer according to the photographing time of a picture or the time interval of frames of camera shooting, and the phase difference is 360o*delta T/T; linear interpolation is adopted for modifying data when the balance wheel pointer and the rocker pointer cannot point to one same scale. The method has the beneficial effects that the influence of large current on the working state of an electronic circuit is avoided, and the method is an improvement of the prior art.
