Abstract
The recent use of single mode fibers in electronic speckle pattern int erferometry (ESPI) shows that it is possible to produce a small and co mpact system for the use even in a hostile environment, Standard singl e mode fibers are easy to handle but cannot preserve the polarization state of the input light when ambient conditions change during long te rm measurements, The quality of the ESPI fringes decreases and the per formance of the measuring system suffers, Under this point of view the correlation of speckle patterns produced by light of different polari zation states is investigated.
