Description

technical field [0001] The invention belongs to the technical field of spectrum measurement, and in particular relates to a method and a device for distinguishing left-handed light and right-handed light of spectral lines of a light source in a magnetic field. Background technique [0002] The famous Dutch physicist Zeeman discovered that when the light source is placed in a sufficiently strong magnetic field (about thousands to tens of thousands of Gauss), the spectral lines split into several polarized sub-spectral lines with very close wavelengths and each discrete polarized sub-spectrum The spacing between the spectral lines is equal, and the size of the spacing is related to the strength of the applied magnetic field Proportional. This discovery made an indelible contribution to the establishment and development of quantum mechanics. In 1902, Zeeman and Lorenz jointly won the Nobel Prize in Physics for this discovery. In order to commemorate Zeeman's achievements, th...
