Holographic experiments: Results of Spacelab D1
Abstract
Holography was used in the D1 Spacelab mission to study bubble motions in liquids and density distributions near the critical point, under reduced gravity. The experiments were performed in the holographic interferometer HOLOP. Principal design of the HOLOP diagnostic system and results of three holographic experiments are presented. The capability of holography to reconstruct a three dimensional image of an object was applied to study Marangoni-convection induced bubble motions in reacting systems and in silicon oils. Changes of the density distribution in a one component fluid (SF6) approaching the critical point were visualized by interference patterns obtained by double exposure holography.
