Abstract. Main features of low-coherence interferometric methods and optical coherence tomography as applied to high-resolution investigation of surface micro relief and microstructure of samples of various materials are considered. Results are presented of practical employment of the two methods for study of a polymer material surface, microstructure of a paper sample, and for analysis of lacquer layer microstructure carried out for assessment of condition of a painting for further restoration with the use of laser technologies.
Keywords: remote testing, microobject, low-coherence interferometry method, optical coherence tomography.
