摘要

A compact Interferometric Tomograph has flown on arnMASER sounding rocket in spring 2002. This originalrninstrument has been developed by Lambda-X (optics)rnand the Swedish Space Corporation-SSC (electronics) tornmeasure 3-dimentional temperature (through refractivernindex) distribution in a liquid while it evaporates thoughrna limited free surface.rnThe tomograph includes 6 interferometers arrangedrnsymmetrically around a liquid cell. The paper describesrnthe module and concentrates on the optical beamrnsplitting and combining original systems that have beenrnimplemented in the compact instrument; holographicrngratings are used to split the sole laser beam into 6rnbeams and to combine the 6 interferometer views on 2rnCCD cameras.rnFinally, 3-dimentional temperature distributionsrnreconstructed from flight data are presented.
