2.71 Optics (Spring 2009, MIT OCW): Lecture 03 - Focusing, Imaging, and the Paraxial Approximation

2.71 Optics

2.71 Optics (Spring 2009, MIT OCW). Instructors: Prof. George Barbastathis, Prof. Colin Sheppard, and Dr. Se Baek Oh. This course provides an introduction to optical science with elementary engineering applications. Topics covered in geometrical optics include: ray-tracing, aberrations, lens design, apertures and stops, radiometry and photometry. Topics covered in wave optics include: basic electrodynamics, polarization, interference, wave-guiding, Fresnel and Fraunhofer diffraction, image formation, resolution, space-bandwidth product. Analytical and numerical tools used in optical design are emphasized. (from ocw.mit.edu)
