【 摘 要 】

We study the linear and quadratic signals of phase demodulation in holographic interferometers, which are realized at interaction of light waves on dynamic hologram of diffusion type in the cubic photorefractive crystals, with taking into account the flexoelectric contribution to the nonlinear response.
