Abstract (en)

[origin: DE19822869A1] The microscope has a probe tip arranged on one side of a transparent sample, which moves in a raster pattern. The tip acts as a point light source. An optical system is arranged on the other side of the sample to focus the light transmitted through the sample and transfer it to a detector unit, or to focus illumination light. The detector tracks the raster pattern in synchronism with the probe tip.
