Optical perspective of the fourier transformers

الملخص EN

The present work is a theoretical and experimental study of a biconvex lens as an optical processor.

The MATLAB software concerning the Fourier optics is used as the basic numerical tool for these work.

In addition to providing functions for calculating Fraunhofer diffraction.

The FFT command enables the calculation of the diffraction pattern of an arbitrary aperture.

Relatively simple MATLAB® scripts are constructed to calculate the diffraction patterns of arbitrary graphics such as geometry shapes, pictures of faces, letters.

This paper also describes a few demonstrations that can be used to reinforce what is covered on the work.

The demonstrations are based on a simple (2F set-up) system.

Diffractive imaging relies on many other technological innovations, including : a CCD camera, digital camera HD (12 Mega Pixels) with a lens (f =7 .23mm).

The experimental results agree with the theoretical calculations.
