Paper Abstract

Selective reflection by interference provides laser protection but is angular sensitive and thus the retinal coverage is inherently limited. It can be shown that thin film stacks are similar in function to holograms and rugates. Eye protection requires optimization of angular coverage and spectral bandwidths. These are intimately related and are a function of the available modulation of the indices of refraction. Maximum protection is obtained by designing the filter such that those rays directed toward the center of rotation of the eye are blocked. Practical flight goggles are being manufactured based on these principles.
