ABSTRACT:
Optical patterns formed by localized optical density or refractive index variations in glass are produced by impregnating a porous glass support with a photolyzable organometallic compound and selectively exposing the glass to a photolyzing light source to cause the photolytic decomposition of the organometallic compound in exposed portions of the glass. The patterns are fixed, if desired, by removing unreacted organometallic compound from the pores.
