ADAPTIVE INTERFEROMETRIC METHOD FOR INITIAL INTERFERENCE ORDER MEASUREMENT IN THE IMAGE OF HIGHLY ORIENTED POLYMERIC TEXTILE FIBERS

摘要

Quite simple interferometric method based on the multi-fringe optical Fourier transform technique is suggested in this article.This method offers a specific and precise technique for the study of highly oriented fibers that produce two or more fringes in the marginal zone of the exit pupil of the microscope objective.The measuring accuracy of the direct initial interference order and the current interference orders in the image of highly oriented polymeric textile fibers is increased.
