Methods of optical measurements of micro displacements, micro vibrations and micro deformations of objects with scattering surface in precision mechanics and precise instrumentation.
Optical measurements and control of surface and volume microstructure of randomly inhomogeneous objects.
Laser and partially coherent interferometry of randomly inhomogeneous media.
Theoretical and experimental bases of laser speckle fields interference are developed in application to laser measurements, methods of holographic and speckle interferometry of micro displacements, vibrations and micro deformations of scattering objects in precision mechanics and electronic engineering.
Theoretical and experimental bases of new class of laser interference measurement systems with a spatially modulated probing beam for testing the microstructure of randomly inhomogeneous objects have been developed. The systems provide realization of new metrological capabilities for the resolution, range and performance of measurements of microstructure parameters of randomly inhomogeneous objects.
Theoretical and experimental basics of new method of interferometry – autocorrelation low-coherence interferometry of structure of layered and scattering media are developed.
New method for reconstructing of object’s image from recording a speckle structure of diffraction field is developed.
Methods of digital holographic and speckle interferometry for determining micro displacements and micro deformations fields of scattering objects are developed.
The theoretical and experimental foundations of a new generation of laser interference retinometers, which are optical systems for diagnosing retinal visual acuity, have been developed.
