Canopy transmittal reflectance control and information display

摘要

A system for controlling the transmittance of electromagnetic energy through an aircraft cockpit canopy, and more particularly a canopy panel structure incorporating selectively energizable liquid crystals therein for controlling the transmittance of the electromagnetic energy and/or for integrating an information display in the canopy panel structure. Also disclosed is a method for controlling the transmittance of electromagnetic energy through an aircraft cockpit canopy utilizing a liquid crystal arrangement which is incorporated into the canopy panel structure.
