Light Scattering
Light scattering occurs when light waves encounter particles or irregularities in a medium, causing the light to deviate from its original path. In Fourier optics, this phenomenon is analyzed using mathematical techniques that represent light as waves and describe how they scatter in different directions. By understanding the patterns created through scattering, we can gain insights into the structure of materials, measure their properties, and even improve imaging techniques. Essentially, light scattering helps us visualize and interpret the distribution and characteristics of objects at microscopic levels.

Light scattering is when light rays hit small particles or molecules in a medium, like air or water, and change direction. This happens because the particles disrupt the path of the light. For instance, when sunlight passes through the atmosphere, it scatters off air molecules, causing the sky to appear blue. Similarly, when light hits fog or smoke, it scatters, making those substances visible. Light scattering plays a crucial role in various fields, including meteorology, biology, and optical technologies, helping us understand phenomena like weather patterns and the colors we see in nature.
