26804 - Visual Optics I
Basic Education
5.1. Methodological overview
The overall objective is to understand the functioning of the human eyeball as an optical imaging instrument, as a first important stage of visual perception, and study the quality of the images obtained with it.
To do this we develop, according to their anatomy, schematic eye models within the paraxial Geometrical Optics.
