In this work, we propose using a Wiener filter to improve the performance of wavefront shaping in disordered media. An analytical expression of the filter entries is obtained for the wavefront shaping algorithm that uses the Hadamard matrix basis.

The method of the dynamic range expansion of the Shack–Hartmann wavefront sensor is discussed. It is based on the use of nonlinear dual focus holographic lenslet arrays with the aberration precompensation. The data concerning the optical setup and

The present study is concerned with wavefront shaping algorithms and their performance in noisy environments. Simple sequential algorithms has quite low initial enhancement rate which makes it hard to overcome strong noise. As a result, more complex

The Talbot effect of the finite phase grating is theoretically, computationally and experimentally investigated. The diffraction of finite periodic phase arrays in the Fresnel region is analyzed according to the scalar diffraction theory. The simulat

The present study considers ab initio computer simulation of the light focusing through a complex scattering medium. The focusing is performed by shaping the incident light beam in order to obtain a small focused spot on the opposite side of the scat

The features of the Talbot effect using the phase diffraction gratings have been considered. A phase grating, unlike an amplitude grating, gives a constant light intensity in the observation plane at a distance multiple to half of the Talbot length Z

A new adaptive method of wavefront sensing is proposed and demonstrated. The method is based on the Talbot self-imaging effect, which is observed in an illuminating light beam with strong second-order aberration. Compensation of defocus and astigmati

The self-imaging phenomenon, or the Talbot effect, is diffraction and interference effect for coherent light that is transmitted through infinite grating or other periodic structure. But in practice, intensity distribution is reproduced with some dis
