摘要： A light source (1) sends towards an object under test (5) a light beam (2) with such a size as to encompass the object (5). Past the object, the beam (2) is processed by an optical processing system (6), comprising a band-pass spatial filter (8) located in the Fourier plane of a converging lens (7), the object (5) being located in the front focal plane of that lens. The filtered beam is collected by a detector (10) that generates an electrical signal representative of the intensity of the field distribution associated with that beam. A system (11) for processing the electrical signal comprises a band-pass filter (12) with temporal cut-off frequencies corresponding with the spatial cut-off frequencies of the spatial filter in the optical processing system (6) and obtains the value of the requested quantity form the electrical signal.

摘要： In order to measure a metal wire of rectangular cross-section advancing in a given longitudinal direction, the device comprises two levers (11, 12) which are mutually rotatably mounted about a transverse fulcrum axis (13). Two pairs of idle rollers (14, 15; 16, 17) opposed in pairs for rolling on opposite faces of the wire are mounted on the levers, equally spaced from and on opposite sides with respect to the fulcrum (13). A restoring spring (18) acts on the levers for bringing the two opposing rollers of each pair near to one another. A transducer (20) for detecting relative movements of the levers (11, 12) is connected to these levers.
