Embodiment 1
[0033] see figure 1 , Embodiment 1 of the present invention, a method for displaying the intensity of polarized light, comprising:
[0034] S1. Turn natural light into linearly polarized light;
[0035] Ordinary light sources emit natural light, and the device used to obtain polarized light from natural light is called a polarizer (Polarizer). Commonly used polarizers include: polarizers, Nicol prisms, etc. The asymmetry between the vibration direction and the propagation direction is called polarization, which is the most obvious sign that the transverse wave is different from other longitudinal waves. Only the transverse wave has polarization phenomenon, and the light wave is an electromagnetic wave. Therefore, the propagation direction of the light wave is the propagation direction of the electromagnetic wave. Both the electric vibration vector E and the magnetic vibration vector H in are perpendicular to the propagation velocity v, so the light wave is a transverse wave, ...

The invention relates to a method for displaying light intensity of polarized light, comprising the following steps of: S1, changing natural light into linear polarized light; S2, judging whether a vibration direction of the linear polarized light is the same as a pre-set polarization direction or not; if so, entering step S3; if not, returning back to the step S1; S3, decomposing the linear polarized light into two components of an X axis and a Y axis; measuring an included angle between the measured linear polarized light and the component of the X axis; S4, collecting information of the light intensity of the components; and S5, processing the information of the light intensity of the components and displaying. The invention further discloses a system for displaying the light intensity of the polarized light. According to the method and the system for displaying the light intensity of the polarized light disclosed by the invention, the light intensity is displayed by utilizing a computer simulation system, so that compared with the traditional system for displaying the light intensity of the polarized light, the system is simpler and more miniaturized.
Description
technical field [0001] The invention relates to the field of electromagnetic waves, in particular to a method and system for displaying the intensity of polarized light. Background technique [0002] As we all know, in the process of light propagation, only one kind of vibration is included, and its vibration direction is always kept in the same plane. This kind of light is called linearly polarized light (or plane polarized light). In daily life, camera lenses, Stereoscopic movies and the elimination of glare from car lights all use the principle of polarization of light. In fact, except for the light directly emitted by the light source, most of what we usually see is polarized light. [0003] The detection of polarized light intensity in the existing technology requires the construction of a sophisticated measuring instrument group, including polarizers, analyzers, light screens, support tables, pillars, detection tables, stepping motors, computers, etc., to detect wave ...
