ABSTRACT:
This invention relates to an active Laser Protection System (LPS) system specifically designed to provide a device that automatically adjusts a protection panel of the device in response to laser light exposure thus preventing a user from being exposed to damaging laser light. In one embodiment the LPS system utilizes a light weight portable goggle type eyewear. In yet another embodiment the LPS system is comprised of contact lenses worn by the user. The LPS system may be used in all light transmissive surfaces where the penetration of laser light is not desired, such as aircraft, spacecraft, vessel, train, and automotive windshields, etc. The LPS system may also be utilized as a replacement window for structures where laser light penetration is undesired. The protection panels utilize Liquid Crystal Displays (LCD) that are activated by laser sensors by means of a microprocessor and power supply means. The device also automatically replaces non-laser visible light that may be blocked because the light was of the same wavelength as the blocked light by projecting that light by means of activating the LCD accordingly by means of the microprocessor.
