Paper Abstract

We report here preliminary work done on possible applications of mixtures of nematic and cholesteric liquid crystals to the optical conversion of ultrasonic images and holograms. We discuss of an original method by which very small changes of pitch of the helical cholesteric structure can be easily measured a s a function of temperature or pressure. Somme experimental results are given and we expose the principles of an experimental system which is being realized and that should permit direct conversion, in real time, of acoustical images and holograms.
