Abstract

A new approach of carbon nanoparticle using for the optical diagnostics of а complex scalar optical field obtained by scattering and diffraction of radiation on a surface with roughness is suggested in this paper. Luminescence of carbon nanoparticles made it possible to register their coordinate position in time. The algorithm for the reconstruction of scalar optical field intensity distribution through the analysis of nanoparticle position was proposed in the paper. The phase map of the optical speckle field was analyzed by a Hilbert transform filter to restore the phase of the entire object. A special attention was paid to the restoration of the phase singularities of the speckle field of the scattering studied object.
