Malus is probably best remembered for Malus's law, giving the resultant intensity, when a polariser is placed in the path of an incident beam. A follower of Laplace, both his statement of the Malus's law and his earlier works on polarisation and birefringence were formulated using the corpuscular theory of light. [1]
The term polarization was coined by Étienne-Louis Malus in 1811. [2] In 1808, in the midst of confirming Huygens' geometric description of double refraction (while disputing his physical explanation), Malus had discovered that when a ray of light is reflected off a non-metallic surface at the appropriate angle, it behaves like one of the two ...
Examples of E-mode and B-mode patterns of polarization. Note that if reflected across a line going through the center the E-patterns are unchanged, while the positive and negative B-patterns get interchanged [23] There are two directions in a polarization pattern - its orientation and its amplitude.
Polarizers which maintain the same axes of polarization with varying angles of incidence [clarification needed] are often called [citation needed] Cartesian polarizers, since the polarization vectors can be described with simple Cartesian coordinates (for example, horizontal vs. vertical) independent from the orientation of the polarizer surface.
Circular polarization can be created by sending linearly polarized light through a quarter-wave plate oriented at 45° to the linear polarization to create two components of the same amplitude with the required phase shift. The superposition of the original and phase-shifted components causes a rotating electric field vector, which is depicted ...
The word has been used for more than 700 years but Taylor Swift’s song “Fortnight” led many curious listeners to look up the word, Merriam-Webster said. “It remains to be seen whether ...
In 1809, Malus further discovered that the intensity of light passing through two polarizers is proportional to the squared cosine of the angle between their planes of polarization (Malus's law), [78] whether the polarizers work by reflection or double refraction, and that all birefringent crystals produce both extraordinary refraction and ...
