Abstract
This chapter deals with the Fourier transformable and image formable properties of a lens using Fourier optics. A special emphasis is placed on the detailed explanation of the Fourier transformable properties of a lens. These properties of a lens are abundantly used in optical signal processing appearing in Chap.11.

Notes
- 1.
In optics, it is quite easy to reduce the size of the image because a lens is available for this purpose. The pulse width of a radar echo can be reduced to improve the range resolution of the radar in a similar manner by electronically realizing a circuit, such as is shown in Fig. 6.21.
