Inparticular the aim is the measurement of the variations in focal length of ophtalmic lenses after undergoing adiffusion process. An interferometric technique has been used and computer simulations have also been carrzedout6 p.application/pdfeng(c) Society of Photo-Optical Instrumentation Engineers (SPIE), 1997InterferometriaLents oftàlmiquesInterferometryOphthalmic lensesinfo:eu-repo/semantics/article5132122019-12-05info:eu-repo/semantics/openAccess
