Fremgangsmåte og innretning til optisk nærfelt-rastermikroskopi på prövelegemer i væsker

摘要

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).
