Low spatial coherence interferometer for high resolved velocity measurements with passive directional discrimination

Not Accessible

Your library or personal account may give you access

Abstract

The visibility of the interference pattern of a Mach-Zehnder-interferometer is investigated in dependence of the spatial coherence. It is demonstrated how the dimensions of the fringe pattern can be shortened significantly due to the low coherence properties. Applications of spatial high resolved velocity measurements in fluid flows are given.
