Paper Abstract

In the present work real time interferograms operations are proposed as solution in flowmeters applications. Cross correlation interference patterns are discussed and proposed as possible physical tools to solve this problem. This experimental proposal is particularly important when micro turbulence produce extremely localized phase mismatch in coherent light beams due to little index refraction variations in the flow channel.
