New Art Forms Based on Polarized Light Jessica Newman, John Noe, Harold Metcalf Laser Teaching Center, Stony Brook Universiy Natural phenomena related to light and optics have long inspired many people, especially artists. Color effects in particular are often a fundamental building block of artistic expression. While color effects can be created in myriad ways, only recently have artists utilized colors created with the help of polarized light as an artistic medium. In 1967 the artist Austine Wood-Comarow [1] created her first polarized light collage, or "Polage," by placing layers of clear cellulose film between two polarizers. She varied the thickness and orientation of each minute piece of cellulose to create a myriad of colors. The artist mounts the finished piece into a light box with a continuously rotating polarizer; this causes the colors to cycle periodically through a sequence of patterns. A related art form based on polarized light has been created more recently by NASA scientist Peter Wasilewski [2], who was inspired by the natural properties associated with light passing through ice crystals. The artist calls this medium Frizion, or "frozen vision." The works consist of enlarged photos of ice crystals viewed with polarized light. Both art forms are based on the same optical effect - that certain materials can modify the polarization properties of light. The light entering the medium is initially polarized using a sheet of Polaroid film, which is similar to what's used in anti-glare sunglasses. In order to reach the observer's eye the light must pass through a second polarizer. However only light whose polarization axis is aligned with that of the second polarizer is transmitted. Color is created by the fact that the polarized light if modified by the substance in a way that depends on wavelength [3,4]. The purpose of this project is to explore the physical principles of polarized light effects, and to demonstrate how these sorts of polarization phenomena can create eye-catching artwork.
