Advance in light filtering technology has implications for LCD screens, lasers and beyond

Blaze Display Technology Co., Ltd. | Updated: Dec 21, 2017

【R&D Department of Blaze Display】Vector polarizers are a light filtering technology hidden behind the operation of many optical systems. They can be found, for instance, in sunglasses, LCD screens, microscopes, microprocessors, laser machining and more. A newly proposed design is a major advance in polarization technology because it enables flexible filtering of a wide range of light sources and generation of new light states.

Vector polarizers are a light filtering technology hidden behind the operation of many optical systems. They can be found, for instance, in sunglasses, LCD screens, microscopes, microprocessors, laser machining and more. Optical physicists from Nanjing and Nankai University, China, and the University of Central Florida, U.S., published details of their new vector polarizer design this week in APL Photonics, from AIP Publishing. The newly proposed design is a major advance in polarization technology because it enables flexible filtering of a wide range of light sources and generation of new light states.

Light waves can oscillate with their back-and-forth motion oriented along different directions, where its polarization describes the nature of this orientation. A traditional polarizer, like a lens from polarized sunglasses, filters out light oscillating along all but one direction. The filtered light is referred to as polarized light.
