Abstract

The use of Helmet-Mounted Displays (HMD) and lasers is becoming widespread throughout the world. The Air Force Research Laboratory (AFRL) Helmet-Mounted Sensory Technologies (HMST) program is currently studying the effects incorporating the various laser eye protection (LEP) technologies into HMD technologies. LEP technologies currently available are absorptive organic dyes or reflective filters such as holograms or dielectric stacks. Because of the overall reduction in light transmittance and selective spectral filtering characteristics of various LEP technologies, compatibility with HMD technologies, and, ultimately, aircrew acceptance must be addressed. This paper will discuss some of the HMST requirements needed to perform adequate LEP and maintain HMD performance. This paper will also include a review of different approaches being studied to meet those requirements.
