ABSTRACT

Photographic Technology Day 3: Ray Tracing, Lenses, and Mirrors

In this lecture, we will study the principles of ray tracing for simple optical components: thin spherical lenses and spherical mirrors. The notion of real/virtual object and real/virtual images will be highlighted as well as the computation of the position and magnification the image. The case of thick lenses will also be mentioned including the notion of nodal and cardinal points. Credits: Speaker:Rom Clement

so um, the um length's work uh is um trained to um deviate um...

[JanPB]

This is OK but it goes nowhere near where the problems lie. I read about lens design as a hobby (I am a mathematician) and I think it would be more interesting to show a bird's eye view of real design process - why one would want to adjust this surface or why to split an element in two, etc.

you need an aerospace degree in order to recite principles of lenses described a thousand years ago?

[wallabee2]

cool but he didnt cover what happens when an object is placed ON the focal point of a thin convex lens, like this --->> ()!! there is no image!!! try it and trace the lines, its cool

im learning this topic in my openrt project in intel my brother works at intel too actually he is on a project called ray tracing in gaming. great vid
