Interference - Holography Studies In Space

The holographic interference device (KGA), specially developed for space conditions, and a number of appendices to this device, which allow to extend its possibilities, is described. Various experimental methods in space based on this device are analyzed. The description of experiments on dissolution of crystals, electrophoretic separation of fractions, heat- and mass transfer, carried out in space on the stations "Salyut-6" and "Salyut-7" are presented.
