Polarization affects the propagation of EM fields at infrared ( IR ), visible, ultraviolet ( UV ), and even X-ray wavelength s. In ordinary visible light, there are numerous wave components at random polarization angles. When such light is passed through a special filter, the filter blocks all light except that having a certain polarization. When two polarizing filters are placed so a ray of light passes through them both, the amount of light transmitted depends on the angle of the polarizing filters with respect to each other. The most light is transmitted when the two filters are oriented so they polarize light in the same direction. The least light is transmitted when the filters are oriented at right angles to each other.

Polarization is important in wireless communications systems. The physical orientation of a wireless antenna corresponds to the polarization of the radio waves received or transmitted by that antenna. Thus, a vertical antenna receives and emits vertically polarized waves, and a horizontal antenna receives or emits horizontally polarized waves. The best short-range communications is obtained when the transmitting and receiving (source and destination) antennas have the same polarization. The least efficient short-range communications usually takes place when the two antennas are at right angles (for example, one horizontal and one vertical). Over long distances, the atmosphere can cause the polarization of a radio wave to fluctuate, so the distinction between horizontal and vertical becomes less significant.

Some wireless antennas transmit and receive EM waves whose polarization rotates 360 degrees with each complete wave cycle. This type of polarization, called elliptical or circular polarization, can be either clockwise or counterclockwise. The best communications results are obtained when the transmitting and receiving antennas have the same sense of polarization (both clockwise or both counterclockwise). The worst communications usually takes place when the two antennas radiate and receive in the opposite sense (one clockwise and the other counterclockwise).
Qualitative data is descriptive information that focuses on concepts and characteristics, rather than numbers and statistics.
Visual display systems have wide-ranging applications in training simulators, serving as comprehensive systems that expand the display field of view by seamlessly combining multiple display units. This paper introduces an innovative spherical display system based on LED technology, designed to achieve close-proximity real-image display within a spherical enclosure. Additionally, we propose a channel division method tailored for this novel LED spherical display to enable efficient display driving. To address geometric distortion issues that arise when rendering flat graphics on a spherical surface, we present a geometric correction method specially designed for LED spherical displays, providing a comprehensive explanation of its theoretical principles and correction process. Experimental results demonstrate that with the implementation of our proposed channel division and geometric correction methods, the number of driving channels for the LED spherical display is reduced, image cropping is minimized, and there is no need for image fusion processing. Corrected images exhibit no distortion, and channel alignment remains continuous without any displacement. This method offers a straightforward operation, requires minimal parameter settings, and is easily implementable, providing a solid foundation for the widespread application of LED spherical vision display systems the future.
Polarization, also called wave polarization, is an expression of the orientation of the lines of electric flux in an electromagnetic field ( EM field ). Polarization can be constant -- that is, existing in a particular orientation at all times, or it can rotate with each wave cycle.
