The PSF describes the response of an image-forming system to a point object. The PSF concept is of fundamental importance in optics since the output of an image-forming system can be simulated as the convolution of the PSF with the input object. In this work, a new graphical user interface has been developed to obtain a real-time measure of the PSF and the corresponding images provided by different lenses and pupils with different sizes and shapes. From a didactical point of view, the proposed method allows students to interpret the results in a visual and heuristic way.2018http://zaguan.unizar.es/record/7950810.1088/1361-6404/aadce0http://zaguan.unizar.es/record/79508oai:zaguan.unizar.es:79508info:eu-repo/grantAgreement/ES/MINECO-FEDER/DPI2015-71256-REUROPEAN JOURNAL OF PHYSICS 39, 6 (2018), [8 pp.]by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
