Abstract

original image

Im Brennpunkt: Die Kombination von differenzieller Interferenzkontrast(DIC)-Mustererkennung und DIC-Polarisationsanisotropie liefert exakte und vollständige Informationen über die dreidimensionale Orientierung einzelner Goldnanostäbe in der Brennebene der Objektivlinse. Die Winkelrotationsmoden und die Kinetik der Goldnanostäbe können dadurch dynamisch aufgelöst werden.
