Variability of Air Temperature,We will show in this chapter that the amplitude distribution in the back focal plane of an aberrationless lens is the Fourier transform* of the amplitude distribution in the front focal plane. This remarkable property has many interesting applications and forms the fundamental principle underlying the subject of spatial frequency filtering.

Characteristic Functions, studied by Hamilton, that characterize the properties of the system completely. The usefulness of this method lies in the fact that just by knowing certain symmetries possessed by the system, one can draw general conclusions about the performance of the system. For example, it will be shown that th

Holography,sensitive material reacts to the . of light falling on it and consequently, after developing and fixing of the photographic plate, one obtains a permanent record of the intensity distribution that existed at the plane occupied by the photographic plate when it was exposed. In this process, the phase
