Human Vision: Optics and Perception

This lecture covers the optics of human vision, explaining the structure of the eye, the formation of images on the retina, and the minimum size of objects that can be resolved. It also delves into magnification techniques using lenses and microscopes, as well as the principles behind telescopes. The concept of wave divergence and diffraction on small apertures are discussed, along with the characteristics of Gaussian beams when focusing light.
