A researcher from Trent University has explored the concept of polarization and how diverse colors appear when materials are placed between a set of polarizers, as part of an effort to use color visualization. for subtle physical concepts that are often only proven mathematically. The researcher also analyzed how these colors can be controlled and the effect of changing the viewing angle, sample orientation, and order of layers between the polarizers on them.
In the study, the researcher used visual examples of concepts related to refractive index – the optical property of materials whose refractive index depends on the polarization and direction of light – such as subtraction. , addition and order of operations.
Typically, formal matrix mathematics is used to explain the noncommutative nature of birefringent addition. However, in this study, published in American Journal of PhysicsResearchers have used color images for the purpose.
“I use the visual language of color to illustrate subtle physics that is often only proven mathematically,” said Aaron Slepkov, author of the study, from Trent University in Canada. a profession that applies polarizing filter coloration in fine art. Austine called his polarizing art or polarizing of collages.
She uses sophisticated layers of cut cellophane and other birefringent polymer films and creates a variety of artworks ranging from small independent works to large installations displayed at research institutes.
“In this work, I clarify the relationship between polarization filtering and the colors observed. I demonstrate how different aspects of birefringence in ordinary household films present opportunities and challenges for their use in art,” says Slepkov.
To generate polarizing filter colors, one simply clamps a birefringent sample between the polarizers that form the polarizing gate. This phenomenon can be seen in many household items that reflect an array of colors and patterns like a kaleidoscope. Clear plastic cutlery, folded kitchen wrap, gift basket film and laminated tape are some of the items.
“The fabrication of birefringent films for the purpose of creating color images is fun and intellectually stimulating. Much of the physical nuances of polarization, birefringence, retardation, and color theory can be observed in this accessible yet expansive endeavor, says Slepkov.
