Patent number: 7688503Abstract: A microscopy system allows to superimpose a light optically generated microscopic image of an object with an electronically generated image. The electronically generated image is composed of two input images, one of which is independent of optical settings of an ocular tube, such as a rotational position and a magnification thereof, and the other input image is dependent of the optical setting.Type: GrantFiled: September 22, 2003Date of Patent: March 30, 2010Assignee: Carl Zeiss StiftungInventors: Karlheinz Hermann, Frank Rudolph, Martin Schneider, Joachim Steffen, Michael Wirth

Patent number: 7254262Abstract: A method for optimizing target quantities for optical precision measuring includes obtaining ancillary parameters from image data of a workpiece which is to be measured. Control data for influence quantities of the target quantities are derived from the ancillary parameters. The control data is derived as follows: by determining the courses of the ancillary parameters depending on at least one influence quantity and the courses of the ancillary parameters are determined in such a way that the courses have a like extremum of the functional dependence from the influence quantities. An overall course of the ancillary parameters is determined and an extremum of the overall course of the ancillary parameters is determined.

Patent number: 7209238Abstract: The invention relates to an interferometer arrangement (1000) having at least one measuring beam path for providing light in an object area, at least one reference beam path and at least one unit for superposing light of the measuring beam path with light of the reference beam path and a unit for detecting an interference phenomenon caused by light from the object area and light from the reference beam path. The invention further relates to a method for measuring the velocity of an object with an interferometer arrangement. In the interferometer arrangement, the unit for detecting has a spatial resolution which corresponds to the characteristic spatial period of the interference phenomenon. In evaluating the time change of the interference signal, the movement of stray centers can be measured. Use of such an interferometer arrangement in a surgical microscope allows to visualize areas of a field of surgery which cannot be accessed with light in the visible spectrum.Type: GrantFiled: December 23, 2005Date of Patent: April 24, 2007Assignee: Carl-Zeiss-StiftungInventor: Christoph Hauger
