Abstract
A method for correcting a wave front analyzer, in which the analyzer detects a signal from an incident wave front to be analyzed (FO), the detected signal providing phase and intensity local information. The method includes correcting the phase computation according to intensity space variations. A wave front analyzer for implementing the method is also described.
