    摘要: A scanning microscope (10) comprises a stage (18) for holding a sample (20), a scan mechanism, a probing system for probing a region (24) of the sample (20), a position sensor (80, 82), and a controller. The scan mechanism is designed for translating the stage (18) between at least two axial positions. The probing system 10 comprises an optical element and a photosensor having a readout region, wherein the readout region extends in a direction (14), which is transverse to an ideal orientation (72) of the stage (18). The position sensor (80, 82) serves for measuring a transverse position (84, 86) of the stage (18) and/or of an orientation (74) of the stage (18). The controller (30) serves for adapting the probing system as a function of the measured 15 transverse position (84, 86) and/or the measured orientation (74).

    摘要: An autofocus imaging system for a microscope system includes a tilted autofocus image sensor that images an oblique cross-section of a slide. The autofocus imaging system focuses multiple sequential overlapping images, which have been taken by the tilted autofocus image sensor, by making a comparison of the multiple sequential overlapping images. An axial position of a tissue layer on the slide can be determined from a polar error signal resulting from this comparison.
