Abstract
Fourier transforms represent an important tool in applied mathmatics . The first yield of its application was in electrical engineering , communications and temporal signal processing . In this work the diffractive properties of a biconvex lens is utilized in a comparative study of the Fourier transform in two dimensional spatial domain .The work includes theoretical calculations of the (2-D) Fourier transforms for certain geometrical object function in the spatial domain . The theoretical calculations made use of the MATLAB® software in creating the aperture's geometry and then calculating its Fourier transform .The digital camera have been utilized to record the experimental results is a (CCD ) camera to record the power distribution of the Fourier transform in the spatial frequency domain
