Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Quality inspection of the gas turbine rotating blades by processing their digital images Abramov A.D. The article presents a new approach to inspect surface microgeometry of devices and mechanisms components after final machining. The approach uses the optoelectronic tools and computer environments. Surface microgeometry inspection results are cited for rotating blades of the aircraft gas turbines subjected to polishing.
