    摘要: The flanks of faults present in a surface produce abnormal reflection of a laser beam during linewise scanning of the surface by a laser beam. This apparatus deflects the angles of reflection from the surface, to indicate the presence of a flank, by a light conducting rod arranged parallel to the direction of linewise scanning for receiving reflected light on its surface and for conducting this light to its end face. The various light rays spread out transversely to the direction of scanning during their passage through the light conducting rod and are detected as they pass through a series of concentric annular apertures spaced from the end face of the light conducting rod. Each aperture is associated with a particular range of angles of incidence irrespective of the point on incidence along the surface of the rod and photoelectric detectors are used to sense the light passing through each aperture to provide the necessary indication of the presence or non-presence of a fault. Several types of transparent light guides are used to concentrate the light from the apertures onto the photoelectric detector and various signal processing circuits are described.

    摘要: Apparatus for determining faults in strip material is disclosed in this application which enables both color defects and distortions of the surface of the strip material to be recognized.It its general form the apparatus illuminates the material surface at a specific angle with white light and an optical system directs the light leaving the surface to a number of photodetection devices which detect the various angles at which light leaves the surface. The deviations of these angles from the direction of specular reflection, or unimpeded transmission, are characteristic of the nature of the distortion of the surface of the strip material. At least the photodetection device which receives the specularly reflected or normally transmitted light and preferably all the photodetection devices, includes two photodetectors, which detect light in different spectral ranges by means of associated beam splitting and filtering devices. In this way color defects such as stains or spots on the surface can also be recognized.

    摘要: Detection apparatus for finding holes in moving webs uses a row of individual mutually sideways displaced stepped mirror strips in combination with a scanning device which periodically scans a light beam from a laser over the individual mirrors of each strip, to generate a scanning light curtain directed at the surface of a web. A detection device comprising a row of individual Fresnel lenses and associated photoelectronic detectors is arranged parallel to the row of mirror strips to receive light transmitted through any hole present in the web. The individual Fresnel lenses focus any light received onto their associated photoelectric detectors the outputs from which signify the presence of the hole. Means are provided for introducing a degree of divergence into the beams deflected from the stepped mirrors and forming the light curtain whereby the light curtain scans a cross the web without gaps.

    摘要: Apparatus for determining faults on strip material includes a scanning device for linewise scanning of a strip of material with a light beam, a first cylindrical lens extending parallel to the direction of the scanned lines and arranged to image the scanned line on a first cylindrical mirror with its focal line at right angles to the direction of the scanned lines.Faults in the surface of the strip material such as dents, bumps and scratches give rise to characteristic deviations or deflection of the scanning light and the arrangement of the first cylindrical lens and first cylindrical mirror produce a convenient spatial distribution of the light in the image field of the first cylindrical mirror which can be detected by suitably disposed detectors to yield information about the nature and location of the fault. The apparatus includes various other optical components to produce a desired grouping of the deviated light beams to aid their identification and subsequent analysis. The apparatus can also operate with transmitted light. The particular arrangements shown are characterized by their compact arrangement.

    摘要: A light smoothing device for rendering a non uniform distribution of light more uniform especially suited for use in line scanning in combination with a light conducting rod which transmits light incident on its surface to its end faces for subsequent detection. The smoothing device has an optical passage with a reflecting interior surface an inlet to the passage and a detector at the other end of the passage. The passage ensures at least part of the light entering the inlet is reflected prior to incidence on the detector.A number of forms of optical passage are disclosed having various reflecting segments of convex, plain or concave curvature.

    摘要: A photo electric light detection device comprising an array of photodiodes is disposed at an end face of a light conducting rod in order to produce an output signal proportional to light incident on the surface of the rod and transmitted to the end face by total internal reflection. The array of photodiodes is subdivided into high and low pass frequency sub-arrays and the output signals from the sub-arrays are summed and processed to compensate for stray light. The device is useful in connection with a line scanner for detecting anomalies in a moving band.
