Paper Abstract

Several methods for detection of a moving object against static bkground in photorefrtive terials (e. g. BSO and BaTiO3) have been reported by using optical phase conjugation or two wave mixing ' 2) Here we donstrate the real-time detection of the moving object using optical phase conjugation in a methyl-orangedopxi polyvinyl alcohol (MO-PVA) film, in which trans-cis photo-isomorization induces optical anisotropy. The present method es two cross-polarized components of the phase conjugate (PC) wave at a wavelength of 515 r.
