Laser Eye Protection.

Abstract

A design for a narrow-band diffractive radiation shield to be fabricated on a helmet visor has been developed and tested. An experimental feasibility study indicates that 99.9% shielding of a specified laser wavelength may be achieved with a visor positioned on the order of 7 cm from the eye (Photopic transmittance is expected to exceed 90%.) Several technical obstacles remain to be overcome before a full-scale workable prototype can be constructed, but shielding efficiencies far better than the 99.9% demonstrated value may become possible as the technology develops.
