Foundations of Optical Engineering and Geometric Optics

Optical systems power everything from the cameras in our smartphones to advanced medical devices and fiber-optic communication networks. Understanding how light behaves and how to manipulate it is the essential first step toward designing these revolutionary technologies. This text-based course guides you through the core principles of optical engineering, transitioning you from a beginner to someone who can confidently analyze light propagation, evaluate lens systems, and understand modern optical components. What you'll learn: - Understand the core principles of geometric optics, including reflection, refraction, and Snell's law - Analyze how light travels through homogeneous media and interfaces using ray tracing techniques - Master the behavior of Gaussian beams and wave optics fundamentals - Evaluate lens performance, optical aberrations, and image formation in simple systems - Explore modern optical applications, including fiber optics and digital sensor integration - Practice solving practical optical design problems through detailed, step-by-step written exercises The course begins with foundational definitions of light, refractive indices, and wave-particle duality before moving into ray tracing, lens combinations, and wave propagation. You will progress from basic geometric concepts to analyzing complex modern optical setups through structured written lessons and self-paced exercises. This course is designed for beginners, engineering students, and hobbyists looking to understand the physics of light and optical design without any prior experience in the field.
