Abstract

Optimization of output characteristics of holograms in BSO crystal by choice of orientation of crystal andpolarization of reading-out light.V.V.Shepelevich, P.P.KhomutovskiMOZyT State Pedagogical Institute, Laboratory of Coherent Optics & HolographyMozyr, 247760, Republic of BelarusABSTRACTThe dependence of the maximum diffraction efficiency im of hologram, which has been recorded in a BSO crystal,and also the dependence of an orientation angle O at which im i reached on the crystal thickness d are investigated. It isshown, that the optical activity and piezoelectric effect qualitatively change the form of dependences im(d) and Otm(d).Key words: piezoelectric effect, optical activity, photoelasticity, diffraction efficiency, orientation angle.
