Resumo: Simple experiments obtained with a laser beam are proposed in this article. Diffraction phenomena and their interpretation in terms of Fourier’s transforms in the spatial domain are discussed in order to introduce some interesting application of the spatial filtering in optics. A straightforward introduction of convolution theorem is also suggested. A stimulus is given to the discussion concerning the utility of Fourier transforms in high school and undergraduate physics teaching.

Serão discutidos os fenômenos de difração e suas interpretações em termos das transformadas de Fourier no domínio espacial, com o intuito de introduzir algumas aplicações interessantes da filtragem espacial em ótica. Será mencionado brevemente o teorema de convolução, além de discutir a utilidade das transformadas de Fourier na Física da Escola Média e de cursos de graduação.Universidade Estadual De Maringá2008-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/306710.4025/actascitechnol.v20i0.3067Acta Scientiarum.
