Paper Abstract

The hardware development of an integrated backscatter fiber optic system for doing dynamic light scattering (DLS) measurements in the constrained microgravity environment of a space shuttle or space station is described. The small size and light-weight system easily fits in a Spacelab Glovebox and ensures maximum safety for the orbiter crew. It offers high precision particle size measurements from dispersions of colloidal particles within seconds. It needs neither onboard optical alignment nor index matching fluid, and it offers sample mixing and shear melting capabilities to study aggregation (flocculation and coagulation) phenomena under both quiescent and controlled agitation conditions. The system can easily be adapted for other microgravity experiments requiring the use of DLS.
