Latest Patents

Vossen's latest patents include an image processing method in microscopy. This invention pertains to the field of image processing in digital pathology. It proposes a method for processing a first digital image, which represents a sample in a region and has been acquired from the sample by means of a microscopic imaging system. The method involves retrieving a sub-region of the first digital image at a first resolution and executing a transform function on the retrieved sub-region. This transform function modifies the content of the sub-region according to at least one metric derived from a second resolution representation of the first digital image.

Another significant patent is related to beam shaping without introducing divergence within a light beam. This optical beam shaper comprises a polarization-dependent phase adjustment member that applies a phase pattern of equal magnitude and opposite sign to two orthogonal polarization states. In a preferred embodiment, the beam shaper is a diffractive element made of a birefringent material, such as a photo-polymerizable liquid crystal polymer frozen in a uniaxial alignment. This diffractive element includes a plurality of zones, each zone having a stepped thickness defining a plurality of steps. The beam shaper can be used to introduce astigmatism to a polarized light beam or to undo the astigmatism to a beam with an orthogonal polarization state. It is advantageously used within a detection device, such as a fluorescence scanner.
