Abstract

In this paper we discuss a fiber optic phase measuring Electronic Speckle Pattern Interferometer. The phase stepping is obtained by stretching the reference arm fiber. We also outline briefly the theory of determining the phase by differentiating the interferogram. Preliminary results obtained with four bucket and differentiation algorithms are presented. 2.
