Powell and K.A. Stetson back in 1960s. The application of those principles coupled with the use of modern high-coherence lasers, powerful computers and digital registration technology helped to raise holographic interferometry to a new level. Today, a single click and a couple of seconds is all that needed to perform operations that used to take days, weeks or even months of hard work of highly professional teams with expensive and bulky equipment.\u00a0\u00a0<\/span><\/p>\n<p><span style=\"font-size: medium\">More about\u00a0<\/span><a href=\"http:\/\/nanotouch.ru\/eng-theory\"><span style=\"font-size: medium\">operating principles<\/span><\/a><span style=\"font-size: medium\">&#8230;<\/span><\/p>\n<p><span style=\"font-size: medium\">\u00a0<\/span><\/p>\n<p><span style=\"font-size: medium\"><a title=\"\u041a\u043e\u043d\u0442\u0430\u043a\u0442\u044b\" name=\"\u041a\u043e\u043d\u0442\u0430\u043a\u0442\u044b\"><\/a>For more information, please contact us (tel.: +7-926-245-62-01; email:\u00a0 <a href=\"mailto:info@nanotouch.ru\">info@nanotouch.ru<\/a>).<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nanotouch Digital Holographic\/Speckle Interferometer \u00a0Equipment designed for surface displacement and surface strain measuring under various loadings &nbsp; GENERAL INFORMATION The NanoDisplacement Visualizer (NDV) is a commercial name of the Nanotouch Digital Holographic\/Speckle Interferometer (DHSI).
