Abstract

The volume holography process in a sensitized fluid is studied. The object of the research is to use forced Rayleigh scattering methods in the measurement of velocity gradients in fluids. The process is divided into three major steps: writing of the hologram; evolution of the hologram under the effect of fluid motion; and reading of the hologram by optical means. The last two steps are discussed with special emphasis on the effects of convection and diffusion as they relate to the hologram deformation and decay.
