Precision diagnostics of three-dimensional geometry of turbine blades for hydroelectric power was presented. The presented technology is implemented on a relatively simple optical-electronic system, carrying out the precise diagnosis of turbine blades in the manufacturing process. An internal software architecture of optical-electronic system which allows to use as receivers of optical radiation any digital camera supported DirectX software interfaces, and any digital projectors as a source of optical radiation was developed. An industrial tests of the prototype of the optic-electronic system for high-precision diagnostics of three-dimensional geometry of turbine blades was carried out. Three-dimensional profile of turbine blade with the linear dimensions of 2,5х2,0x1,0 m was obtained. The possibility of performing accurate non-contact measurements in manufacture conditions using proposed precision diagnostics of three-dimensional geometry of turbine blades for hydroelectric power was shown.
