Abstract:
Specklephotography with twoexposition digital recording of specklestructure of diffraction field and numerical specklegram processing for measurements of scattering object micro displacement is considered. Methods for realization of specklephotography technique with recording of digital specklegrams in far field diffraction area and in field of focused image are discussed. Natural and numerical experiments to obtain measuring information on object micro displacement are performed.
Keywords:
specklepattern, digital specklephotography, Fourier-specklegram, diffraction halo, spatial spectrum, interferogram.
