Diffraction using an amplitude grating object of truncated inverted parabolic shape
Hamed, Abdallah;
Abstract
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 pm, while the
object width is kept constant at 5 pm. The theoretical results of the intensity distribution are
graphically represented using MATLAB program. Finally, a discussion and conclusions are
presented.
