Patent number: 12007544Abstract: A method for capturing an image of an object includes guiding a scanning beam along a scanning trajectory over the object using a scanner, with the scanning movement being periodic in a direction. The scanning movement is sampled at a first sampling frequency for detecting and capturing a current position of the scanner as position values and radiation from the object is captured as captured sampling values at a second sampling frequency. Current values of the amplitude and the phase of the scanning movement are calculated. A current amplitude, phase and/or frequency and future changes in the amplitude, phase and/or frequency over time are calculated. An image grid is set, with grid elements being assigned the sampling values based on times at which the scanning beam crosses or will cross at least one boundary of the grid elements.Type: GrantFiled: September 4, 2019Date of Patent: June 11, 2024Assignee: CARL ZEISS MICROSCOPY GMBHInventors: Tobias Kaufhold, Frank Klemm, Thomas Egloff, Mirko Liedtke

Patent number: 10254524Abstract: Beam deflection units in light-scanning microscopes are usually arranged in planes that are conjugate to the objective pupil. The scan optics, which is required for generating the conjugate pupil planes, is complicated and not very light efficient. The invention is intended to enable a higher image quality, simpler adjustment and a lower light loss microscope. The optical system comprises a concave mirror (36) for imaging a respective point of the first and second beam deflection units (30A, 30B) onto one another. The concave mirror (36), the first beam deflection unit (30A), and the second beam deflection unit (30B) are arranged such that the illumination beam path is reflected exactly once at the concave mirror (36). A first distortion caused by the concave mirror (36) and a second distortion of the imaging caused by the first and second beam deflection units (30A, 30B) at least partly compensate for one another.Type: GrantFiled: November 11, 2015Date of Patent: April 9, 2019Assignee: Carl Zeiss Microscopy GmbHInventors: Daniel Schwedt, Tiemo Anhut, Matthias Wald, Beate Böhme, Tobias Kaufhold
