Patent number: 6717125Abstract: Arrangement and method for focus monitoring in a microscope with digital image generation, preferably in a confocal microscope. The arrangement provides an additional, rotatably supported transparent optical component in the known construction of a microscope in front of a main beam splitter arranged in the beam path in the area of a parallel illumination beam path. According to the method, the images required for focus monitoring are recorded with a transparent optical component inclined by angle +&agr; or −&agr;. The images are checked for correlation of the image contents in the direction of beam displacement by pixel-by-pixel displacement. The determined displacement &Dgr;s at optimum correlation represents a measurement of the instantaneous focusing or defocusing. The suggested solution for focus monitoring is applicable with slight adaptations for all microscopes outfitted with digital image-generating methods and arrangements.Type: GrantFiled: September 12, 2002Date of Patent: April 6, 2004Assignee: Carl Zeiss Jena GmbHInventor: Guenter Schoeppe

Patent number: 6037583Abstract: A control system for a scanner is disclosed, especially for a laser scanning microscope, with an oscillating motor for driving an oscillating mirror serving for the linearly oscillating deflection of a beam bundle, with a control unit for supplying the oscillating motor with an exciting current which is variable with respect to the control frequency, frequency curve, and amplitude, with a function generator which is connected with the control unit, and with a measurement value transducer for obtaining a sequence of information about the deflection positions of the oscillating mirror.The measurement value transducer is connected with the function generator by way of a logic unit for determining correction values for the exciting current. Accordingly, it is advantageously possible, by evaluating the information supplied by the measurement value transducer about the actual deflection position of the oscillating mirror, to determine correction values with the assistance of the logic unit.Type: GrantFiled: January 21, 1998Date of Patent: March 14, 2000Assignee: Carl Zeiss Jena GmbHInventors: Gunter Moehler, Guenter Schoeppe, Sebastian Tille
