The readout properties of the specklegram recorded in a photorefractive Bi12SiO20 (BSO) crystal plate have been investigated by observing the Young fringes and the polarization change of the light transmitted from the BSO plate. The Young fringes can be obtained without an analyzer by any linearly polarized readout beam; they have higher visibility than those obtained from a photographic plate specklegram, since the specklegram recorded in the BSO crystal can be read out by the spatial distribution of both the degree of polarization and the azimuth angle of polarization. Selective interference of a kind is performed.
