Abstract:
The stability of an earlier obtained solution to a phase problem in optics is investigated with respect to the small random errors in measured intensity distributions. Based on calculations of the signal—to—noise ratio, the feasibility of calculational formulas for creation of the phase reconstruction algorithms implemented in wave front sensors and systems of optical control is analyzed.
