Abstract

Interest in the liquid crystal television (LCTV) kinoform has been reported recently by several investigators. The technique requires a modulation depth of about 2π, which most of the commercially available LCTVs cannot attain. We discuss an experimental study of generating an LCTV kinoform in which the the modulation depth is limited by π. The major drawbacks of the ir phase variation are that, compared with 2π variation, it reduces the diffraction efficiency as well as the space bandwidth product to a degree of about one-fourth. Verification of these findings is reported.
