Patents by Inventor Karl-Heinz Geier

Karl-Heinz Geier has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20050185274
    Abstract: A method for generating a stereoscopic image of an object includes providing a microscope arrangement defining an imaging beam path coming from the object. The microscope arrangement includes an objective mounted in the beam path to define an intermediate image plane. A reflective element is placed in or close to the intermediate image plane or in or close to a plane conjugated to the intermediate image plane. The reflective element is driven at a clock frequency so as to reflect respective images of the object alternately toward the left and right eyes of an observer.

  • Patent number: 6882473
    Abstract: An arrangement for generating a stereoscopic image of an object for viewing by an observer includes an imaging optic for imaging the object and defining an imaging beam path as well as an entry pupil and an exit pupil. Illuminating optics illuminate the object by providing an imaging beam coming from the object and passing through the imaging optic and along the imaging beam path. The imaging beam is sectioned in the imaging beam path into two component beams at one of the following locations: in the exit pupil, near the exit pupil or at a position along the imaging beam path which is optically conjugated to the exit pupil, thereby forming stereoscopic sectioned images. The stereoscopic section images are allocated in a clocked manner to the left and the right eyes of the observer. The invention is also directed to a method of generating a stereoscopic image of the object.

  • Patent number: 5835264
    Abstract: The invention is directed to a method and arrangement for generating stereoscopic images of an object. The method includes the steps of illuminating an object with an illuminating beam; masking the illuminating beam to generate a first component beam to illuminate the object at a first angle and provide a first image of the object to a first viewing eye; again masking the illuminating beam to generate a second component beam to illuminate the object at a second angle and to provide a second image of the object to a second viewing eye; and, alternately repeating the last two steps at a frequency above the flicker frequency of the human eye. In the arrangement of the invention, a beam generating device alternately generates first and second illuminating beam components which illuminate the object via illuminating optics at respectively different angles to produce respective images of the object.

  • Patent number: 5583690
    Abstract: In a Faraday microscope for examining specimens with stray magnetic fields in a reflected light beam path with a magnetic indicator film arranged in front of the specimen, the influence of the specimen on the indicator film is evaluated with the indicator film arranged as the termination of the microscope objective, the indicator film advantageously being arranged on an optically transparent substrate. The indicator film and substrate are taken into account in the optical calculation of the microscope objective.
