Abstract:


    Time varying, inhomogeneous refractive index fields are every-where, from hot air rising above a fire and mirages above hot roads in the summer, to gases flowing from pressurized containers, and mixtures of different liquids. We present a novel method for imaging and volumetric reconstruction of time-varying refractive index fields, based on the Background Oriented Schlieren (BOS) technique developed in the fluid imaging community [Meier 2002].
