Description

technical field [0001] The invention relates to the field of light measurement, in particular to a light polarization degree measuring device. Background technique [0002] The asymmetry of the polarization vibration direction of light with respect to the propagation direction is called polarization. It is the most obvious sign that transverse waves are different from longitudinal waves. Only transverse waves can produce polarization. Therefore, the polarization of light is another example of the wave nature of light. In the plane perpendicular to the direction of propagation, it includes transverse vibrations in all possible directions; the light whose transverse vibration is symmetrical to the direction of propagation is called natural light (unpolarized light), and the light whose vibration loses this symmetry is collectively called polarized light. Any target on the earth's surface and in the atmosphere will produce different degrees of polarization due to its own charac...
