Reconstruction techniques of holograms from Spacelab 3.

Area of Science:

• Space science
• Fluid dynamics
• Crystallography

Background:

• Buoyancy-driven fluid transport is well-understood in Earth's gravity.
• Microgravity environments alter fluid dynamics, making buoyancy less dominant.
• Understanding these altered transport mechanisms is crucial for space-based research.

Purpose of the Study:

• To describe the Fluid Experiment System (FES) optical system.
• To detail holographic reconstruction techniques for microgravity experiments.
• To discuss the multiuser and reflight capabilities of the FES.

Main Methods:

• Development of a holographic Fluid Experiment System (FES).
• Deployment of FES aboard the Shuttle orbiter in Spacelab for microgravity research.
• Investigation of triglycine sulfate (TGS) crystal growth in low-g.

Main Results:

• The FES successfully acquired holographic data during its first flight on Spacelab 3.
• Detailed examination of holographic reconstruction techniques was performed.
• The system's design facilitates maximum data acquisition in low-g.

Conclusions:

• The Fluid Experiment System (FES) is a valuable tool for studying microgravity fluid dynamics.
• The holographic approach provides rich data for experiments like crystal growth.
• Future experiments leveraging the FES capabilities are proposed.
