摘要： An optical arrangement of the Michelson interferometer type having a measuring arm for measuring optical properties of at least two mutually spaced regions in an optically transparent and/or diffusive object. A reference arm has a path length variation unit which generates a periodic change in path length for the radiation in the reference arm. Arranged in the measuring arm upstream of the object is a detour unit. The detour unit imparts a detour which is larger than at least one second measuring beam into at least one measuring beam. The detour unit selects a detour to be equal to a distance between regions to be measured in the object. Using the optical arrangement the object is irradiated with the aid of a number of measuring beams corresponding to the number of regions. In each case two measuring beams have an optical path difference which corresponds to a geometrical distance between two regions. Each reflection beam of the measuring beams which is reflected by one of the regions is superimposed in an interfering fashion with a third beam having a temporal variation in path length, and is detected. This arrangement can carry out “in-vivo” measurements of distances, thicknesses, at and/or in the human eye with the minimization of measuring errors within a sub-second time. The object does not have to be fixed during the measurement.

摘要： A distance measuring apparatus is provided which utilizes a light-section method capable of measuring both close objects and far away objects without adjusting the dynamic range of an imaging camera. The apparatus comprises: an image acquisition section for imaging reflected light which has been emitted from the apparatus, has passed through a slit, and has then been reflected off the surface of a target object; an emission control section for controlling the emission time of the slit light during the time an image is being scanned by the image acquisition section, and for changing the intensity of the received light in the image acquisition section; and a distance calculation section for calculating the distance to the object based on the image taken by the image acquisition section and a positional relationship between a light emission position of the slit light and an image position.

摘要： Apparatus and methods of measuring three-dimensional position information of a point on the surface of an object. In one embodiment, the method includes the steps of providing two sources of radiation having a spectral distribution, illuminating the surface with each of the sources to produce a first fringe pattern, moving the first fringe pattern to a second position, generating a first wrapped cycle map, estimating fringe numbers in the first fringe pattern, changing the first fringe pattern, moving the second fringe pattern to a second position, generating a second wrapped cycle map, estimating fringe numbers in the second fringe pattern, and determining position information in response to the estimated fringe numbers in the second fringe pattern and the second wrapped cycle map. In another embodiment the apparatus includes two sources of radiation having a spectral distribution and being coherent with respect to one another, a control system for moving each of the sources relative to each other, a detector positioned at the point on the surface of the object to receive radiation illuminating the point on the surface of the object, and a processor for receiving signals from the detector. The processor calculates position information of the point on the surface of the object in response to the movement of the sources and the radiation received at the point on the surface of the object.

摘要： A method for non-destructively inspecting the wall thickness of a component, where the dimensions of the component or of the component surface are measured, substantially without making any contact, and are described by digital data. In accordance with the present invention, a multiplicity of the component's surface points, which substantially completely describe the component, is automatically calculated in a three-dimensional coordinate system. Starting from each of the surface points, going out in one direction that runs perpendicularly to the surface point into the material, one scans for at least one opposite surface point. The wall thickness of the component at the surface point is ascertained as the distance between the surface point and the at least one opposite surface point. The component is visually displayed and, in the visual display, surface points are highlighted for which the wall thickness falls below and/or exceeds one or more predefined values. The present invention renders possible a reliable and complete, automatic determination of wall thickness and a rapid evaluation of components and/or of critical wall thicknesses.

摘要： An interferometric measuring system including a movable member having a measurement reflector attached thereto, a stationary member having a reference reflector attached thereto, a light source for providing a light beam, and an optical support block having first and second beam splitters mounted thereon. The first beam splitter is operable to convert the light beam into a first pair of orthogonally polarized beams and arranged to direct one of the first pair of beams along a reference path to the reference reflector and the other of the first pair of beams along a measurement path to the measurement reflector to create a measurement interference pattern between the first pair of beams for determining a position of the movable member. The second beam splitter is operable to form a second pair of orthogonally polarized beams and arranged to direct the second pair of beams along support block measurement paths to the reference reflector. The second beam splitter is configured to form a correction interference pattern between the second pair of beams for determining error in the position of the movable member due to movement of the optical support block.

摘要： In a thickness reducing management for pipes in pipe lines, limited proper parameters which cause erosion and corrosion of the pipes are selected and with these parameters a pipe thickness reducing speed evaluation model formulas are constructed, and by making use of the model formulas thickness reducing amount of the pipes is evaluated. Thereby, conventional difficulty of formulating a proper pipe thickness reducing estimation model formula in view of actual pipe material and pipe inner fluid state because of too many possibly influential parameters causing pipe thickness reducing due to erosion and corrosion, and conventional difficulty of performing highly reliable pipe thickness reducing management are overcome.
