WebJul 22, 2024 · Figure 1: Diagram illustrating a thin lens acting as a phase transformation over the input field In this section, we'll show how to mathematically modeling a thin lens. Suppose that a monochromatic wave is incident on a thin lens, On z = 0, let the complex field of the wave be represented as: (1) u ( x, y, 0; t) = U ( x, y, 0) e − i ω t WebFor a thin lens, the refracted ray is traveling in the same direction as the incident ray and is approximately in line with it. The behavior of this third incident ray is depicted in the diagram below. Now we have three incident rays whose refractive behavior is easily predicted.
