Schmidt number modulation

Besides kinetic applications, which are still to be fully realized, hydro-dynamic modulation is useful for Schmidt number and diffusion coefficient measurements not only in Newtonian fluids but also in viscoelastic polymer solutions (Ostwald fluids) [291].

The Rotation Modulation Collimator was originally conceived by Mertz [9] as a technique to encode an image formed in the focal plane of an optical Schmidt-telescope to allow electronic read-out by a photomultiplier. The technique was soon adapted to image forming in X-ray astronomy by Schnopper et al. [11], and was successfully used in a number of rocket flights to localize X-ray sources with good precision [12,14]. In 1974 the UK ARIEL-V and in 1975 the NASA SAS-3 satellite was launched both equipped with RMC systems. The source localizations provided by ARIEL-V and SAS-3 led to the discovery of many new X-ray sources and the identification of the optical counterparts of several sources [13,15,16].
