Optical profilometry of nanofibre mats
WebOptical profilometry represents another noncontact surface metrology technique that uses an optical microscope in which light is split into two paths by a beam splitter placed … WebHere, we demonstrate an optical scattering-based scanning method that uses a probe nanofiber to locally scatter the evanescent field of a sample nanofibre. The method does not damage the sample nanofiber and is easily implemented by only using the same equipment as in a standard fiber-puller setup.
