Abstract
New coherence methods of microobject parameter measurements are analyzed in connection with the development of the automatic data processing systems, of the phase0shifting holography methods, as well as with the appearance of new active elements permitting to carry out autodyne measurements. The simple method of parameter inspection of microobject vibration is based on usual optical microscope with TV camera is discussed. The method based on the phase- shifting interference pattern consequence analysis using the Fourier transformation is given. For the first time the possibility of the returning of the non-harmonical vibration spectrum of the object in phase-shifting holographic interferometry has been considered. The semiconductor laser autodyne systems have been used to elaborate new technologies of fast-changing processes control. The use of semiconductor laser autodyne for the diagnostics of the microsaccidic eye movements, known as eye tremor, whose amplitude does not exceed several microns has been shown.
