A theoretical model of an inverted parabolic function is considered to represent an amplitude object. The intensity distribution of the diffraction pattern is calculated by applying Fourier transformations and convolution operations upon the object. A computer program is constructed to plot the intensity distribution of the diffraction pattern obtained. In the computations, the maximum heights of the inverted parabolic function are taken to be 2.5, 5, and 10 mm, while the object width is kept constant at 5 mm. The theoretical results of the intensity distribution are graphically represented using MATLAB program. Finally, a discussion and conclusions are presented.
