Abstract

An optical structured illumination of 3D object as a light band method of wear measurement and defects detection of a contact wire network on railways, tram, trolleybus lines and similar systems of vehicles electro-supply is presented. The experimental device can extract main technological wire parameters, as its remaining height with rms value down to 0.1 mm. Also the cross-sectional area of the wire can be measured with rms area noise value of 1.5mm², which is sufficient for confident decision-making related to the automatic wire wears and defects.
