Jd. Trolinger et al., HOLOGRAPHIC PARTICLE IMAGE VELOCIMETRY IN THE FIRST INTERNATIONAL MICROGRAVITY LABORATORY ABOARD THE SPACE-SHUTTLE DISCOVERY, Applied optics, 35(4), 1996, pp. 681-689
In January 1992 the Space Shuttle Discovery carried the first Internat
ional Microgravity Laboratory into Earth orbit for eight days. One of
the many experiments carried out during the orbit was a combined study
of triglycine sulfate crystal growth from solution and fluid-particle
-dynamics studies in microgravity. Optical diagnostics included holoca
meras to provide concentration measurements and three-dimensional part
icle tracking. More than 1000 holograms that were recorded in space ha
ve been analyzed since the flight, providing a wide range of interesti
ng conclusions about microgravity, crystal growth, and particle dynami
cs. This paper focuses on the results of holographic particle-image ve
locimetry experiments and provides an excellent example, along with ne
w techniques, for exploiting holography for particle and flow diagnost
