The study of light, known as optics, has fascinated scientists, philosophers, and artists for centuries. Light is not just a fundamental aspect of our everyday lives; it is also a profound force in the universe. From the moment humanity first discovered fire to the modern era of lasers and fiber optics, our understanding of light has grown exponentially. In this chapter, we will delve into the fascinating world of optics, exploring its history, the nature of light, its behavior, and its applications in various fields.
Optics and photonics have revolutionized our understanding of light and its applications. From fundamental concepts to advanced technologies, the study of optics and photonics has paved the way for groundbreaking discoveries and practical innovations. We delve into the principles of lenses, mirrors, and optical systems, and discuss the formation of images in cameras, microscopes, and telescopes. We also touch upon advanced imaging techniques such as holography and tomography.
