Abstract

The work is devoted to an experimental study of the digital holographic interferometry method for flaw detection of optical fiber preforms (preforms).  Flaw detection of the production of optical fibers plays an important role.  This article describes the process of digital holographic shooting and image processing of holograms. Based on the Leith–Upatnieks optical scheme, a holographic interferometer scheme has been developed, in which a hologram is recorded directly on a CCD array.  A series of experiments on holographic interferometry of flaw detection of optical fiber blanks has been carried out.  Holographic interferometry allows you to record objects in different states. Based on the experimental data, the possibilities of the method are studied and the possibility of its use is justified, its advantages over other analyzers of optical fiber preforms are also presented.
