The team of AlphaMicron Inc. and Kent State University proposes a novel LC technology, the dynamic polarizer, as a light control system for Battlefield Airmen and Pilots. The dynamic polarizer technology shares the performance capabilities of AlphaMicron’s e-Tint LC light control technology: instantaneously fails-to-clear, millisecond switching times, and customizable tint and color. However, the dynamic polarizer improves on the performance by expanding the transmission window and providing the capability of continuously adjustable transmission levels for the operator. The technical objectives of the Phase I work will focus on investigating all factors impacting the transmission window of the device. This work includes modeling device performance, testing new plastic substrates and conductive layer materials, developing liquid crystal mixtures, and preparing prototype devices. Work completed over the course of the Phase I program will establish a performance baseline for the dynamic polarizer, as well as establish a catalog of component materials for next generation eyewear and display visor light control films utilizing dynamic polarizer technology.

Phase II research efforts focus on advancing the development of the switchable polarizer light control films for pilots and warfighters. The light control films utilize AlphaMicron's propriety liquid crystal technology to provide adjustable tint on demand with millisecond switching times, fails to clear, and excellent optics. Research efforts include the development and fabrication of single and double curved light control films for use in eyewear and display visor applications.Through fabrication and characterization of prototype devices, a catalog of materials suitable for pre-production level prototypes will be created. This strategy provides a crucial element on the path from prototypes to commercial products using the technology.
