For designing optical systems with tunable anamorphic ratios, we extend Hopkins’s design procedure, which is restricted to spherically symmetric elements, with fixed optical powers. This extension is used for proposing a Gaussian system that purpos

For extending focal depth we employ a set of transparent concentric rings, which are coded with the Barker sequences of length L. At the neighborhood of the paraxial focal plane, these transparent masks generate an axial uniform distribution, which i

Here, we review some basic mathematical tools that are useful for describing the image formation process, in optical instruments. In parallel, along this chapter, we develop the notation that I employ through this book. As a roadmap, in Table 1.1, we

Here, we develop a nonconventional, yet very useful, treatment of scalar diffraction. This simple elegant description complements the classical treatments of wave propagation, as it is commonly used in Fourier optics.

In several research branches of optics systems, one faces inevitable trade-offs between two figures of merit, which are obtained from functions that are Fourier transform pairs. The celebrated Heisenberg uncertainty principle is the classical example

In this chapter, we revisit the basic principles, behind the pioneering efforts for implementing varifocal lenses, as a good example of wavefront engineering. Next, we define the concept of phase conjugated pairs (PCP), which is applied for linking v

In this chapter, we discuss some figures of merit on image quality. First, we briefly revisit the definition of Strehl ratio, which was initially used for setting a tolerance to defocusing. We note that Rayleigh’s quarter wave rule finds practical

Quite often image science was associated to the analysis of photographic images (Dainty and Shaw in Image science. Academic Press, London, 1976). However, in modern parlance, image science encompasses the basic principles and the engineering practice

We discuss the Gaussian design of a device that controls the scale, in an anamorphic fashion, of Fraunhofer diffraction patterns. The device uses two pairs of varifocal cylindrical lenses. For spherical lenses, the optical powers can be predicted by

In this chapter, we introduce the concept of wavefront engineering by discussing the use binary masks, which generate irradiance distributions capable of displaying the variations of the impulse response with changes of optical path difference (OPD).
