Method of scanning a sample with a light beam focused by a microscope objective lens and scanning light microscope

Upstream a microscope objective lens, a polarization direction of a light beam is tilted with a first electro-optical deflector between a first polarization direction with which the light beam is deflected by a first polarization beam splitter by a first angle and a second polarization direction with which it is deflected by a second angle. With a second electro-optical deflector, the polarization direction of the light beam is tilted between a third polarization direction with which the light beam is deflected by a second polarization beam splitter by a third angle and a fourth polarization direction with which it is deflected by a fourth angle. By rotating the polarization direction of the light beam by means of the first and second electro-optical deflectors in a coordinated way the light beam is tilted about a fixed point in a pupil of the objective lens.

Subpixel line scanning. A slide scanning device comprises a plurality of line sensors (112a, 112b, 112c), each comprising a plurality of pixel sensors. Each line sensor is offset from an adjacent line sensor by a fraction of a length of each pixel sensor, and generates a line image of the same field of view at its respective offset. For each of a plurality of positions on a sample, a processor combines the line images of the same field of view, generated by the plurality of line sensors at their respective offsets, to produce a plurality of subpixels for each of at least a subset of pixels within the line images of the same field of view, and generates an up-sampled line image of the position comprising the plurality of subpixels. Then, the processor combines the up-sampled line images of each of the plurality of positions on the sample into an image.
