Malus' law and wave plates are essential tools in optics for understanding and manipulating light polarization. Malus' law quantifies the transmitted intensity based on the orientation of polarizers, while wave plates transform the polarization state, enabling various technological applications.
Malus' law describes how the intensity of polarized light changes when passing through a polarizer. The transmitted intensity depends on the relative orientation between the light's polarization axis and the polarizer's axis. If both axes are aligned, the transmitted intensity is maximal and if they are perpendicular, the transmitted intensity is zero.
Waveplates are optical devices used to modify light polarization by introducing a phase shift between the two orthogonal components of polarized light. A quarter-waveplate (λ/4\lambda/4λ/4) introduces a 90° phase shift, converting linearly polarized light into circularly polarized light (and vice versa) when positioned at 45°. For other angles, it produces elliptically polarized light. A half-waveplate (λ/2\lambda/2λ/2) introduces a 180° phase shift, effectively flipping the polarization direction of linearly polarized light.
Liquid crystal displays (LCDs) rely on polarization to control light transmission and generate visible images, making polarization one of the key principles behind modern display technologies.
