Some polarization properties of volume holograms in Bi_12SiO_20 crystals and applications

Optimization of low-noising hologram characteristics in photorefractive piezocrystals

“…THEORETICAL ANALYSIS Using techniques described above the dependence of maximum cross-polarization gain Gx on orientation of the holographic grating vector for Bi12SiO20 crystal (Fig.1) is investigated in given paper. The cross-polarization gain G for the case of linearly polarized light beams is determined in accordance with the formula G= , (5) …”

Real-time displacement and tilt analysis by a speckle technique using Bi12SiO20-crystals

“…The photoinduced phase shift is small; d An ,¢ ~'1 (it is of the order of X 1/30). The amplitude can therefore be written as A'(u')"-Ao(u' ) 1 -i Xl An , (4) where the terms on the order of An 2 and higher are neglected. In eq.…”

Real-time contour holography using BSO crystals

“…Electro-optical crystals such as Bil2SiO20 (BSO) are appropriate for real time recording. They were already used for real-time holography [5][6][7][8] and speckle applications [9]. For the application to be described, the BSO crystal was biased with a transverse electric field E 0 in the 110 crystallographic direction.…”
