Abstract

Holographic rejection (notch) filters are used for eye protection against laser radiation because they allow high visual transmission since they reflect only a narrow spectral bandwidth. Their angular dependence, typical of diffractive and interference filters, can be minimized or avoided when the filters also perform as holographic optical elements with particular optical configurations. These configurations are described for two eyewear geometries, and possible options between theoretical design, practical filter construction limitations, and spurious images are investigated.
