Introduction to Optical Engineering and Lens Design

Optical systems power everything from the cameras in our smartphones to advanced medical imaging devices and autonomous vehicle sensors. Understanding how to manipulate light through lenses and mirrors is the key to engineering these cutting-edge technologies. This course guides you through the foundational physics of geometrical optics and the practical methods used to design reliable optical systems. You will transition from understanding basic light propagation to analyzing aberrations and optimizing complex lens assemblies for modern applications. What you'll learn: - Understand the core principles of geometrical optics, including refraction, reflection, and wave propagation - Analyze optical aberrations to identify and correct image distortions in lens systems - Design basic lens configurations, from single elements to multi-lens imaging systems - Apply computational optimization techniques to improve image quality and system performance - Integrate modern optical designs with digital sensors like CMOS cameras and LiDAR receivers - Evaluate optical tolerances to ensure designs can be manufactured reliably The journey begins with fundamental terminology and the physics of light before progressing to ray tracing, aberration control, and modern computer-aided design workflows. You will read through practical design scenarios and solve conceptual exercises to solidify your understanding. This course is designed for aspiring engineers, physicists, and technology enthusiasts new to the field, requiring no prior background in optical design.
