Abstract |
AB |
[DE] Herkömmliche Methoden zur Rasternahfeldmikroskopie an Probekörpern in Flüssigkeit setzen das Vorhandensein einer ausreichend glatten, reflektierenden Probenoberfläche zur Detektion der Schwingungsbewegung der Lichtleitfaserspitze und damit zur Abstandsregelung zwischen Spitze und Oberfläche voraus. Durch das erfindungsgemäße Verfahren, bei dem die Schwingungsbewegung vorzugsweise mit Hilfe eines weitgehend parallel zur Probenoberfläche verlaufenden Lichtstrahls ohne Reflexion an der Probenoberfläche detektiert wird, können beliebige Proben in nahezu jeder Flüssigkeit untersucht werden. Untersuchen von durch die Flüssigkeit an der Probenoberfläche hervorgerufenen Veränderungen. <IMAGE>
[EN] The microscopy method involves using a laterally oscillating optical fibre point immersed in the sample fluid, with regulation of its distance from the sample surface by detection of the oscillation movement. The latter movement is detected via a light beam directed parallel to the sample surface without reflection, with evaluation of the refraction image of the light beam provided by a light detector, e.g. a photodiode (5). |
