As most up-to-date applied sciences are not any longer discipline-specific yet contain multidisciplinary ways, undergraduate engineering scholars could be brought to the rules of mechanics so they have a robust historical past within the easy rules universal to all disciplines and may be able to paintings on the interface of technological know-how and engineering disciplines.

The image becomes a two-dimensional array of intensities (or gray levels). The light intensity is thus sampled by the camera, with constant sampling intervals x and y. The image analysis is done on discrete two dimensional functions. The Fourier transform must be extended to such discontinuous functions; in this case it is called the Discrete Fourier Transform (DFT). The DFT is an approximation of the Fourier transform of a function, as a sampled function is an approximation of a continuous function.

In the case of some interferometric techniques or in the case of photoelasticity the carrier is directly the wave length of light. In what follows the analysis of a sinusoidal carrier will be introduced as a mathematical model for all types of carriers. One must remember that by utilizing Fourier transform methodology all the integrable functions can be represented by their expansion in Fourier integrals. The carrier can be thought of as a sinusoidal function generated by a rotating vector E and the phase of the carrier at a point of coordinate x is deﬁned as the total angle rotated by the vector up to that point.

This aspect poses a difﬁcult problem because the leakage depends on the relationship of the frequency of the signal and the size of the observed region. The smaller the pitch of the sinusoidal function is with respect to the size of the observed region the less important the problem of leakage becomes. The opposite occurs when the above relationship grows. In this ﬁeld the utilization of windows becomes mandatory because it will be necessary to separate some portion of the spectrum from other portions.
