Description

Technical Field

[0001] The present invention relates to the technical field of target characteristic measurement and sensing mechanism, and in particular to a full-angle multi-modal polarization characteristic measurement sensing mechanism and a testing method thereof. Background Art

[0002] Light has three basic properties: wavelength, intensity, and polarization. Light in nature includes fully polarized light, partially polarized light, and unpolarized light (natural light). Natural light is a light wave in which the light vector is equally distributed on a plane perpendicular to the propagation direction, and the amplitude is equal in all directions. Unpolarized natural light is scattered by the medium, reflected by the object, etc., causing the vibration direction of the light vector to be asymmetric with the propagation direction, thus becoming polarized light.

[0003] Polarization of light refers to the characteristics of the direction of electric field vibration in light waves, while polarized light refers to light that only exhibits electric field vibration in a specific direction after being processed by a polarizer. The polarization characteristics of different targets refer to the differences in the characteristics of the electric field vibration direction of the light waves they reflect or transmit.

[0004] In nature, light has different polarization states, including linear polarization, circular polarization, and no polarization. The electric field vibration direction of linearly polarized light is only in one plane, which can be horizontal or vertical; while the electric field vibration direction of circularly polarized light changes sinusoidally over time in one plane. These polarization states may be different for different target objects, depending on factors such as the material, shape, surface roughness of the object, and the angle and wavelength of the incident light.

[0005] Since different target objects have different characteristic polarization properties, the polarization characteristics of light can be used to detect the real target objects in complex environments, which is more efficient and accurate than traditional detection technologies. In addition, the polarization characteristics of light are also widely used in communications, remote sensing, biomedicine and other fields. For example, in the field of communications, the polarization characteristics of electromagnetic waves can be used to increase the capacity and reliability of signal transmission; in the field of remote sensing, polarization information can improve the resolution of optical observations and help identify and classify objects; in the field of biomedicine, polarized light imaging technology can be used to observe the microstructure and functional changes of biological tissues.

[0006] Therefore, the polarization characteristics of different targets is a complex research field with broad application prospects. By deeply studying the polarization characteristics of different targets, we can promote the continuous development of science and technology. The existing technology lacks a mechanism that can measure and perceive the full-angle polarization characteristics of different targets, different illumination, different temperature, and different detection methods, so it is urgently needed to be improved.
