    • A device and method for improving a visualization of detected defects (1) in a substantially planar transparent strip (70), most preferably in a strip of a film. The device is arranged with a light source (90, 92) in order to substantially illuminate the width of the transparent strip (70), focusing means (50, 52) provided with an optical axis (100), in order to focus the light which is coming from the transparent strip (70), a detector (10, 12), in order to detect defects (1) on the transparent strip (70) and means (80) for displacing the transparent strip (70) in its longitudinal direction. The transparent strip (70) is arranged in a first plane between the light source (90, 92) and the focusing means (50, 52), and where the optical axis (100) is arranged in a second plane in order to focus the incoming light to the detector (10, 12) by means of the focusing means. The light from the light source is inclined with respect to the lateral direction of the transparent strip (70) and the light source (90, 92) is arranged in the second plane in order to obtain a high intensity.

    • The invention relates to an analysis machine for the cleanness of perforated strips.
      The invention enables the direct non-destructive measurement, without image conversion, of the pollution by particles of the surface of plastic strips that are relatively transparent and perforated; which is done by using in an automatic analysis machine, a supporting and guiding means (10) of the strips (30) to be analyzed, the said means comprising a transparent revolving cylinder (12) provided with at least one groove (13) of small depth in which are arranged opaque masks (14) which practically superimpose with the perforations (31) of the strip (30) to be analyzed; which is to prevent the disturbance and deterioration of the recording due to the light rays emitted by the lighting means located near the device (10), light rays that crossing the perforations (31) of the strip (30), dazzle the associated recording means.
      The main application of the device that is the object of the invention concerns the inspection of the cleanness of photographic films or magnetic tapes, at all stages of their utilization, and more precisely the use of the said device in automatic analysis machines checking the cleanness of the said photographic films or magnetic tapes for the whole of their surface.

    • The present invention concerns a method and a device for counting and characterising defects on a photographic support.
      According to the method which is the object of the present invention, the support (1) is caused to pass in front of an optical density measuring device (2), the density values given by the said device being analysed for the purpose of detecting, counting and characterising the defects, the said method being characterised in that the defects are detected for a first speed V1 at which the support (1) passes and in that the data necessary for the counting and characterisation of the defects thus detected are captured and stored for a second speed V2 at which the support passes, less than V1.
      Application to the processing of photographic films.
