Abstract:
The diameter of a running elongate object such as an optical fiber is measured by means of two opto-electronic systems. The systems have optical axes which are perpendicular to each other and to the running axis of the object. Each of the systems further includes a microscope lens for forming a blurred image of the object on a strip of photodetectors. The systems combine their images in an apparatus which calculates an accurate position of each edge of the object by interpolation.
Abstract:
The invention relates to a spectrometer/colorimeter apparatus comprising an opto-electronic card (12) with the essential components of the apparatus mounted thereon, and in particular a spectrometer (14) having an inlet slot (16) and a strip (18) of photodetectors (20), and two optical fiber measurement paths (28) and two calibration paths (26), with the ends of the optical fibers being superposed in the inlet slot (16) of the spectrometer. The apparatus is particularly intended for use in an industrial environment.
