Patent number: 7456973Abstract: The invention serves for the contour measurement and/or deformation measurement of an object, particularly a tire or a structural component of a composite material. The object is irradiated with light, particularly structured light, that is emitted by a radiation source and consists, in particular, of coherent light or partially coherent light, especially laser light. The light reflected by the object is picked up by a camera with an imaging sensor. In order to improve the image quality, a first image is produced with a first adjustment of the camera and/or the radiation source which is adapted to a first image region (13). In addition, a second image is produced with a second adjustment of the camera and/or the radiation source which is adapted to a second image region (12). Both images are combined (FIG. 5).Type: GrantFiled: April 27, 2004Date of Patent: November 25, 2008Assignee: Steinbichler Optotechnik GmbHInventors: Hans Steinbichler, Roman Berger, Thomas Mayer

Patent number: 6590668Abstract: A method serves the direct phase-angle measurement of radiation, in particular of light radiation which is reflected from a body. The body is exposed to coherent radiation. The radiation reflected from the body is imaged by an imaging optical system (6) in an image plane in which a sensor is located. A reference radiation generated in accordance with the shearing method is superimposed on the sensor. The phase of the radiation from the body is determined from the measurement signals of the sensor. To improve such a method, the imaging optical system (6) possesses a diaphragm (11) having one or two apertures (12, 13) (FIG. 2a).Type: GrantFiled: December 7, 1999Date of Patent: July 8, 2003Assignee: Steinbichler Optotechnik GmbHInventors: Rainer Huber, Junli Sun, Bernd Leitner, Hans Steinbichler

Patent number: 5841030Abstract: A process is disclosed for determining the vibration characteristics of a body by modal analysis. The body is made to vibrate at different frequencies and optical interference images of the body are recorded for the different frequencies. The interference images are analyzed on the basis of a mathematical/physical model, in view of the vibration characteristics at predetermined points, and the thus obtained information about the vibration characteristics of said points is subjected to a modal analysis.Type: GrantFiled: April 14, 1997Date of Patent: November 24, 1998Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Wolfram Honsberg, Raymond Freymann, Franz Winter, Hans Steinbichler

Patent number: 5289264Abstract: An apparatus is used for ascertaining the absolute coordinates of an object (1). Said apparatus includes a light source (6), projection optics, in particular a projection objective (7), a projection grating (2) which is projected onto the object (1) through the projection optics (7) to form an image, a sensor (5) for receiving the light (4) reflected from the object (1), and an objective (8) projecting the light (4) reflected from the object (1) onto the sensor (5). In order to enable the simple determination of the absolute coordinates of the object (1), the projection grating (2) and/or the sensor (5) are rotatable. There is provided an evaluation unit which evaluates the signals (shots or pictures) of the sensor (5) at least two different angle positions of the projection grating (2) or of the sensor (5) and determines the absolute coordinates of the object (1) therefrom.Type: GrantFiled: September 25, 1992Date of Patent: February 22, 1994Inventor: Hans Steinbichler

Patent number: 5155363Abstract: A method for direct phase measurement of radiation, more particularly light radiation, which is reflected by a body or object with a diffusely reflecting surface. In order to make possible measurement of the phase with the production of a single image, the object or body is irradiated with coherent radiation having a predetermined frequency. The reflected radiation is used to produce an image in an image plane using an image forming optical system, a sensor with a plurality of preferably regularly arranged sensor elements being located in the plane. There is a superimposition of reference radiation on the sensor with the same frequency and with a defined phase relationship. In the case of directed object rays coming from a mirror-like body or object, the reference beam is set so that one period of the interference field produced on the sensor by the superimposition of the object and reference beams covers at least three sensor elements.Type: GrantFiled: September 13, 1990Date of Patent: October 13, 1992Inventors: Hans Steinbichler, Jorg Gutjahr

Patent number: 4964770Abstract: In a process of making artificial teeth horizontal or other contour lines are generated on the ground tooth stump and on adjacent surfaces, said lines are detected by optoelectronic means, the data which have thus been acquired are used to compute the three-dimensional shapes of the tooth stump and of the required artificial tooth, and an artificial tooth having the shape which has thus been determined is then made by processes known per se.Type: GrantFiled: July 12, 1988Date of Patent: October 23, 1990Inventors: Hans Steinbichler, Jurgen Willer

Patent number: 4111557Abstract: The specification describes a method for the optical determination of departures in shape, changes in shape, and changes in position. In the method by means of light rays patterns are produced on the object and the patterns are represented by a photoelectronic device. Light rays originating from a coherent light source are projected by lenses or mirrors or holographically as a line or lines and/or point arrangements on an object, which are represented by means of an objective on an optoelectronic receiving device. In it they are converted into electric pulses, which after analog-digital conversion in an electronic computing unit are stored and are digitally coordinated with spatial coordinates. The data so obtained are compared with the data, obtained in the same manner, of the same object before its change in shape or position or with the data of an ideal or real object determining its ideal shape.Type: GrantFiled: March 25, 1976Date of Patent: September 5, 1978Assignee: OPTO Produkte AGInventors: Hans Rottenkolber, Hans Steinbichler

Patent number: 3976380Abstract: A method and apparatus for nondestructive testing of articles by holography in which light beams from a virtual point source of laser light and from an observation point are reflected by a reflector toward the same point on the object being checked. The light beams when extended beyond the reflector intersect on an ellipsoid having the point source and the observation point as foci. A plate having a hologram of the article is interposed between the observation point and the reflector and flaws in the object being tested show up on the plate as interference lines when the object is modified in shape by a mass influence such as a temperature change, or a change in pressure thereon, or by vibrations.Type: GrantFiled: March 11, 1974Date of Patent: August 24, 1976Assignee: Opto-Produkte AGInventors: Hans Rottenkolber, Hans Steinbichler
