ABSTRACT:
A stowable laser eye protection system is provided as a solution for protecting the eyes of pilots and other vehicle operators and optical sensors such as during critical phases of flight and for general protection against a wide range of spectral wavelengths. A stowable laser eye protection system provides protection that can be manually or automatically extended and retracted. For example, by installing flexible laser protective films on rollers at each window of an aircraft cockpit, the protection can be put in place during taxi before take-off and stowed when the aircraft is a safe distance away from a potential threat area such as after reaching a particular altitude. A similar activity could be used for approach and landing, where the protection is extracted when the aircraft approaches a threat condition or critical phase of flight and retracted after landing.
