Optical electronic measuring systems and laser technologies for scientific and industrial applications

The novel results of the R and D activity of TDI SIE SB RAS in the field of the optical measuring technologies, as well as laser technologies for solving actual problems are presented. The metrological characterization of a perspective Fresnel method for high precision measuring the dimensions of objects is investigated. An optoelectronic noncontact method using diffractive optical element (DOE) for the 3D inspection of article holes is presented. A structured light method and system testing results for noncontact inspection of wire wear and its defects for train electro-supply network are discussed. For permanent noncontact bearing position inspection of oil-drilling platforms on Sakhalin coast (Russia) under extreme temperatures (± 40°C) we have developed optical-electronic method and system SAKHALIN. Multifunctional laser technological system LSP-2000 equipped by two Nd-YAG lasers was developed for cutting, welding and surface micro profiling with ablation process (working range of 3 x 3 x 0.6 m 3 , positioning error less than 10 μm). Safety of Russian nuclear reactors takes 100 % noncontact 3D dimensional inspection of all parts of fuel assemblies, including grid spacers. Results of development and testing the specialized high productive laser measuring machine, based on structured illumination, for 3D inspection of grid spacers with micron resolution are presented. For safety increasing of Russian railways TDI SIE has developed and produced automatic laser diagnostic system COMPLEX for inspection of geometric parameters of wagon wheel pairs for running train (speed up to 60 km/hr.), which is used successfully on Russian railways.
