A mais interessante delas é a de termos uma imagem convergente, que pode ser vista projetando sobre uma tela, por exemplo / Abstract: We perform ray tracing analysis on the imaging of white light objects by diffractive elements by means of the main direction of the rays. We explore the possibilities that the symmetry of a set of two bidimensionally acting diffracting elements intermediated for a pinhole offers. The most interesting of them is that we have a convergent image, that can be seen projecting on a screen, for example / Mestrado / Ótica / Mestre em Física
