Testing two techniques for wavefront analysis. Specific applications and comparative study

This work focuses on the description of two different techniques for characterizing wavefronts: by using Shack-Hartmann (SH) sensor and by using Point Diffraction Interferometer (PDI). Moreover describes application examples of each in recent research, and finally a comparative study of both techniques on a single optical system is performed.This work was supported by the “Agencia Estatal de Investigación” (AEI) and the “Fondo Europeo de Desarrollo Regional” (FEDER), under Project FIS2016-77319-C2-2-R of the Spanish “Ministerio de Economía, Industria y Competitividad”.Postprint (published version
