Abstract

Now that we know what light is and its properties, in this chapter we will focus on understanding how we have learned to generate and detect it, as all artificial light sources of light require the conversion of some kind of energy into electromagnetic radiation. The main thread of this chapter is understanding how this conversion takes place, identifying the part of the electromagnetic spectrum where the different types of light sources have the best properties and discovering which are the most efficient of them. At the end of the chapter, we will focus on the optical systems that can detect light and their recent application to artificial vision.
