The experiment-calculated method has been developed of determination of rigidity of mechanical junction "composite-metal". Schematic circuits have been developed, engineering of electronic circuits of microcontroller, amplifier of US excitation and generator of acousto-optical modulator conducted. Manufactured electronic and optical-mechanical units of hardware and software complex. Two two-phase digital stepper drivers 2DM542 from JMCo and bipolar stepper motors used. Testing of movement system conducted, which demonstrated visual improvement of quality of radio-wave image for account of rise of resolvability to 0.5 mm and positioning precision.
