Abstract

This study proposes a method for reconstructing the wavefront phase of coherent radiation using a physical model of light propagation, instead of Fourier transforms. The method uses a back-propagating beam with a conjugated optical phase to efficiently account for real properties of optical elements. Experimental demonstration is provided of beam formation in a real optical system with a pre-defined transverse intensity distribution with the help of a phase spatial light modulator (SLM), whose state is calculated by using the proposed method on Zemax software for light propagation modelling.
