AFRL re-ups affiliation with longtime liquid crystal industry partner to meet DOD needs

The image depicts AlphaMicron Inc., or AMI’s prototype progression over the course of 20 years. AMI’s first dimming proof of principle prototype from 1997 was eventually integrated into a Full Complex Curvature Helmet F-35 Visor prototype for the U.S. Department of the Air Force in 2017 to help mitigate pilots’ difficulties managing light transmission during flight. The initial collaboration between AFRL and AMI resulted in the creation of e-Tint, an electronic tint-on-demand liquid crystal technology that can be applied to flexible plastic substrates, such as pilot visors, instead of traditional glass. e-Tint switches from clear to dark faster than an eye can blink — about 0.1 of a second— and is fail-safe in a power outage. This technology was used to create the world's first electronic switchable eyewear which was field tested by the U.S. Army and is now being issued to soldiers through the Approved Protective Eyewear List.  In addition to current applications, the technology is being developed for augmented reality applications and see-through displays, where simultaneously controlling ambient and display light is important, said AMI’s Chief Technology Officer and Chief Executive Officer Dr. Bahman Taheri.(U.S. Air Force photo)
