Title:
SELECTIVE COMMUNICATION USING MULTIPLE SEPARATED POLARIZERS
Document Type and Number:
WIPO Patent Application WO/2024/064906
Kind Code:
A3
Abstract:
A polarizer is an optical filter that lets light waves of a specific polarization pass through while blocking light waves of other polarizations. It can filter a beam of light of undefined or mixed polarization into a beam of well-defined polarization, that is polarized light. The presently disclosed technology is generally directed to using two or more separated layers of polarized film or other polarized structures to selectively block incoming light to a user's eyes or electromagnetic radiation (EMR) to a sensor, which serves to selectively communicate information to the user or sensor. In some implementations, one or more of the layers of polarized film is moveable or rotatable to actively adjust the EMR blockage.
