Title: Method for measuring the groove pitch of a cylindrical spiral cable wrapping with helical grooves in translation, and apparatus for implementation thereof
Inventor: LIBERT JEAN-FRANCOIS
IPC: G01B11/14
Filed: 1986-02-17
Abstract: Method for measuring the groove pitch of a cylindrical spiral cable wrapping with helicoid grooves in translation, and apparatus for implementation thereof. Method for measuring the groove pitch of a cylindrical spiral cable wrapping with helicoid grooves in translation. The spiral cable wrapping is illuminated using a longitudinal light slot. A generatrix of the spiral cable wrapping is observed over a determined period of time using a camera 8 with aligned charge transfer photoelements. The charges resulting from the illumination are then transferred into one or more read registers. The analog signals generated are compared with a threshold signal, and then converted into logical signals. A specific number of translations is selected, to which the numbers of the corresponding photoelements are matched. The pitch is calculated by locating transition distances of two successive logical signals corresponding to a groove or to two adjacent grooves. These operations are repeated continuously.
