Paper Abstract

The holographic interferometer in two directions of observation (HOLIDDO) instrument is dedicated to the characterization of transparent media which evolve with time in a microgravity environment. It is a multiuser facility, the heart of which is an exchangeable experimental cell adapted to the investigator's requirements. Optical characterization is made either by direct viewing or by interferometric holography imaging in two perpendicular directions which permits reconstruction of a 3-D object. The optical bench allows a depth of field of 30 mm with a resolution better than 50 micrometers . An Fe-LiNbO3 crystal has been selected for storing holograms with a large lifetime, which is necessary for a real time survey. The laboratory model, which is functionally representative of the future flight unit, is now available for testing space experiments.
