Abstract

Holographic recording characteristics using a photoinduced surface deformation in a side-chain type azo-polymer film were investigated. Corona charging at temperatures above the glass transition temperature increased the diffraction efficiency of the recorded hologram from 0.24% to about 30% and the relief depth from 20 to 350 nm. © 2001 Elsevier Science B.V.
