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.

Method for correcting a wave front analyser and analyser implementing said method

An instrument () for characterizing an optical system, includes: at least one primary source () for emitting an illumination light beam (FE); an optical device for directing the illumination beam (FE) onto the optical system (L) to be characterized; a wave front analyzer () adapted for receiving a beam from the optical system (L); and a unit for processing the measure signals from the wave front analyzer (), adapted for providing characterization information of the optical system (L). The instrument further includes a scattering member () substantially provided in the focal plane of the optical system (L) so as to create a secondary source generating a secondary beam flowing through the optical system (L) and further directed towards the wave front analyzer.
