Digital holography in visible range, phase retrieval

SPAR method

Femtosecond holography


ICI-LLS method

Holograms processing and retrieval

The main results in this area are:

1. Developed modern methods for reconstructing the wavefront from off-axis holograms:

  • The SPAR method with sparse sets for noise suppression
  • The ICI-LLC method based on the rule of intersection of confidence intervals for the resolution increase
  • The method of subtracting the wavefronts, excluding the preliminary phase scan

2. Method of femtosecond off-axis digital holography with time domain

3. Realization of holograms reconstruction by the method of least squares in tomography
