I. What is Polarized Light?

Polarized light refers to light waves in which the oscillation direction is restricted to a certain direction during propagation. Typically, this is achieved using polarizing devices such as polarizing films or polarizers. Polarized light can be used to improve image quality, enhance sensor performance, and boost the efficiency of optical devices.

II. Working Principle

The generation of polarized light is based on the oscillation direction of light waves. In natural light, the oscillation direction of light waves is random, but through the use of polarizing devices, the oscillation direction of light waves can be restricted to a specific direction, resulting in polarized light. Common polarizing devices include polarizing films, polarizing prisms, and polarizers.
