Paper Abstract

A chromatic performance simulation is introduced to achieve a sensitive transmission/attenuation property of aircrew laser eye protection (LEP) visors. The simulation optimizes dye selection for best visual performance during the design phase without actually manufacturing test pieces. Prototype daytime and nighttime LEP in-helmet type visors are manufactured to demonstrate that careful dye selection can realize attenuation by a factor of more than 1000 at four laser lines in the visible to near-infrared spectral range, and simultaneously realize the high visibility required for aircrew job performance. Optical measurements and several key ballistic protection tests prove that both LEP visors meet military use requirements.
