20220373777 · 2022-11-24 ·

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.

11573412 · 2023-02-07 · ·

In high-resolution scanning microscopy, a sample is excited by illumination radiation to emit fluorescence radiation in such a way that the illumination radiation is focused at a point in or on the sample to form a diffraction-limited illumination spot. The point is imaged in a diffraction-limited manner into a diffraction image on a spatially resolving surface detector, wherein the surface detector has a spatial resolution that resolves a structure of the diffraction image. The sample is scanned by means of different scanning positions with an increment of less than half the diameter of the illumination spot. An image of the sample is generated from the data of the surface detector and from the scanning positions assigned to said data, said image having a resolution that is increased beyond a resolution limit for imaging. For the purposes of distinguishing between at least two predetermined wavelength regions in the fluorescence radiation from the sample, a corresponding number of diffraction structures are generated on the surface detector for the at least two predetermined wavelength ranges, said diffraction structures differing but having a common center of symmetry. The diffraction structures are evaluated when generating the image of the sample.
