In industrial production, research, and quality assurance, this technology ensures the detection of the smallest height differences and enables the evaluation of roughness or structures at a microscopic level. With the ongoing miniaturization of components and increasing demands on surface quality, interferometry is becoming increasingly important as a measurement technique.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n                    <\/div>\r\n                                        <\/div>\r\n                            <div class=\"ArticleMultiConContentBlock \" id=\"69e366792d043\" data-type=\"text\">\r\n\r\n                                                                    <div class=\"ArticleMultiConContentBlockTitle headline_default headline_h2\">\r\n                        <h2>Fundamentals of Optical Measurement Methods<\/h2>\r\n                <\/div>\r\n                                                <div class=\"ArticleMultiConContentBlockText text_default\">\r\n                        <p data-start=\"47\" data-end=\"381\">The physical principle of interferometry is based on the superposition of light waves.
