Detection of Small Displacements Using of Optical Diffractive Correlator (JTh4A.7)

Presenter: Svitlana Bugaychuk, Institute of Physics, NAS Ukraine



We are developing method to precise displacements based on mutual transverse shift between two diffraction gratings included in correlator. Intensity distribution over diffraction orders unambiguously expresses value of small grating displacement.
