Paper Abstract

The structure and operation o a holographic intererometer that employs photorefractive crystals (o the sillenite Family) as reusable recording materials and computer image processing or rapid and precise interpretation o the fringe patterns are discussed. Different types of two-wave mixing (2WM) and four-wave mixing (4VM) were applied to optical testing by timeaverage and double..exposure hoaographic intererometry. A very convenient matching was found in the setup or the BTO crystals and usual Re—Ne lasers, when the exposures were o r.lOs or light energy densities o 4 x lO" W/cm2.
