The present article presents a new concept for a light optical field microscope developed after two decades of attempts to find a portable, yet versatile and capable, instrument for extra-laboratory research. Emphasis was put on a portable microscope with polarizing capabilities, yet versatile enough to perform in other configurations. After testing almost every available model made during the last century, the Goren microscope, as it is called now, was developed and tested in various field conditions. The new design, fashioned as two prototypes, is expected to be inexpensive if commercially produced. Still, it can be readily modified to perform as a bright-field, dark-field, phase-contrast, or polarizing instrument. The historical background of field microscopes is briefly presented in context of this new invention.

The Ideal

In this chapter we study with the tools developed in Chapter 3 the basic models that are the foundations of light–matter interaction. We start with Rabi dynamics, then consider the optical Bloch equations that add phenomenologically the lifetime of the populations. As decay and pumping are often important, we cover the Lindblad form, a correct, simple and powerful way to describe various dissipation mechanisms. Then we go to a full quantum picture, quantizing also the optical field. We first investigate the simpler coupling of bosons and then culminate with the Jaynes–Cummings model and its solution to the quantum interaction of a two-level system with a cavity mode. Finally, we investigate a broader family of models where the material excitation operators differ from the ideal limits of a Bose and a Fermi field.
