Application of a confocal scanning laser holography (CSLH) microscope to the study of fluid flow in a microgravity environment is described herein. This microscope offers a new, non-intrusive means to determine three-dimensional density gradients within solid objects, fluids, and plasmas, including flames. The index-of-refraction is determined from the phase measurements of the microscope, which is a function of the object temperature and composition. The object being studied is a fluid-cell chamber, which is heated and cooled on opposing walls to produce a steady-state fluid flow due to convection and heat transfer. The holograms are created from the interference of a “known” reference beam with an “unknown” object beam. A three-dimensional amplitude and phase image of the object is produced by the reconstruction of many holograms, where each hologram represents a scanned point inside the object.
