【 摘 要 】

The paper outlines some issues related to optical sensors based on the diffraction method which are used as a part of the devices to control the outer diameter and eccentricity of a single-core electric cable. The conversion function which allows calculation of the diameter of cylindrical objects regardless of their position in the tested area is considered. The calculations are based on the diffraction method to detect shadow boundaries of the object in two-dimensional optical sensors that use a divergent laser beam. The obtained results can be used to develop precise optical instruments to control the outer diameter and eccentricity of the object in a cable industry.
