Diffraction Control Methods of Extended Products’ Diameter

Popis výsledku v původním jazyce

In this article the methods of measurement of extended objects’ geometry on the basis of effect of light diffraction which can be applied to products’ technological control of wide ranges of diameters from the smallest to the biggest are described. The way allowing to minimize the influence on result of measurement of diameter of thin fibers of the disturbing factors, such as excessive flare of area of the central maximum at measurement of small diameters of micron range is described. It is considered the diffraction method allowing to increase to units of micrometers the resolution of the optical measuring converters used in devices to technological control of cylindrical extended products of a big diameter such as: cables, wires, cords, etc. The transformation function allowing to calculate diameter of cylindrical products irrespective of their situation in a control zone on the basis of a diffraction method of delimitation of its shadow in optical two-coordinate converters with the dispersing laser bunch is offered and experimentally confirmed. The shown results can be used for development of high-precision optical devices of technological control of outer diameter and eccentricity of products for cable, pipe and other fields of the industry.
