Abstract
Abstract We describe recent advancements in laser light scattering hardware including intelligent single card correlators, active quench/active reset avalanche photodiodes, laser diodes, and fiber optics which wereused by or developed for a NASA Advanced Technology Development program. We then preview a spaceshuttle experiment which will employ aspects of these hardware developments.Introduction A new generation of hardware has been developed for NASA's Advanced Technology Development(ATD) program in laser light scattering (LLS).2 These developments are coupled with both ground-based and flight proposals which have been accepted through the peer-reviewed NASA ResearchAnnouncement (NRA) selection process. This combination is culminating in a number of laser lightscattering flight hardware instruments. We will discuss the primary modules used in the laser lightscattering program and will single out for review a space shuttle LLS experiment which uses many of these components.
