ABSTRACT：The novel results of the R & D activity of TDI SIE SB RAS in the field of the optical measuring and laser technologies, for solving safety problems in atomic and oil industry, as well as in railway transport are presented. 3D profilometer with submicron and nanometer resolution using Linnik white-light interferometer and testing results of industrial system for measuring surface defects of fuel elements are given. The metrological characterization of a perspective Fresnel method for high precision measuring the dimensions of objects is investigated. Results of development and testing the industrial system prototype for 3D inspection of nuclear grid spacers with micron resolution based on DOE structured illumination are presented. Ensuring the safety of running trains is the actual task for railways. Using high-speed laser noncontact method on the base of triangulation position sensors, TDI SIE has developed and produced automatic laser diagnostic system Complex for inspection of geometric parameters of wheel pairs (train speed up to 60 km/hr.), which is used successfully on Russian railways.We have developed an optical structured light method and an optical-electronic system for automatic noncontact distant measurements of wear and defects detection for a contact wire electro-supply network. For permanent noncontact bearing position inspection of oil-drilling platforms on Sakhalin coast (Russia) we have developed optical-electronic method and produce system SAKHALIN. Experimental results and technical performances are presented.
