An undergraduate experiment to illustrate spatial transfer function concepts in Fourier optics

Abstract

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

I learned it through the hologram

“…For students without a solid background in mathematics and physics, it is usual to emphasize the in two dimensions (2D) -generally approached mathematically -becomes a tool directly related to the physical properties of the waves and involved in the formation of an image. It allows the introduction of the free space transfer function and the usual convolution tools used in the field of linear filtering [4]. The propagation then becomes a convolution between the initial field and the 2D FT of the free space transfer function [5].…”
