Images are critical to a variety of fields and industries ranging from entertainment, to security, to medicine In this chapter we define and classify images, and then classify several basic ways in which they can be produced. The wavelength/frequency range in which electromagnetic (EM) waves (light) are visible is only a tiny fraction of the entire electromagnetic spectrum. Maxwells Rainbow Although light waves spread as they move from a source, often we can approximate its travel as being a straight line geometrical optics. Reflection and Refraction What happens when a narrow beam of light encounters a glass surface? Reflection: 1 1 ' = Refraction: 2 2 1 1 sin sin n n = Law of Reflection Snells Law 1 2 1 2 sin sin n n = n is the index of refraction of the material. For light going from n 1 to n 2 : n 2 = n 1 2 = 1 n 2 > n 1...
