Title: Method of and apparatus for determining the diameter of a wire rod or tube having a circular cross-section by means of photo electric scanning
IPC: G01B11/10
Filed: 1972-06-05
Abstract: 1391963 Measuring diameter photoelectrically EXATEST MESSTECHNIK GmbH 5 June 1972 [4 June 1971] 26043/72 Heading G 1 A In an apparatus for measuring the diameter of an object 10, in which the field of view of a photocell arrangement 34 is periodically scanned across the object, the photo-cell output, which is representative of the diameter, is modified to remove errors caused by lateral movement of the object. Each arrangement 34 includes a rotating mirror (16), which performs the scanning, a photomultiplier (18) which views the object, and a light source/photodiode unit (22/26) which produces marking pulses indicative of the mirror position, Fig. (not shown). Illumination of the object is provided by two extended light sources 121, 1211. Any movement of the object in direction Y 1  results in a change in the spacing between the marking pulse signal and the "object" signal from arrangement 34 1 . This change is analyzed mathematically in an analog circuit, Fig.5 (not shown) forming part of correction circuit 44. The other input to circuit 44 is a reference value of the diameter to be measured. The "corrected" reference value is thus the output from circuit 44 and is supplied to a comparator 40 to be compared with the measured value of the diameter. The difference is displayed at 42. Hence each photo-cell arrangement both senses the object diameter and provides a signal to correct the output of the other photocell.
