AO Slides

These are some images about adaptive optics from Wikipedia as well as the lectures from the short course. It's a pretty neat topic. There's all kinds of theory and real hardware - how you understand light and how one actually corrects for imperfections in the eye, telescope etc.

Zernike Polynomials - how one represents errors in a wave of light.
A screen shot of a point-like object imaged through a "messed up" optic, like my eye...

How turbulent air as well as diffracted light "mess with" a pure point imaged by a telescope.

How one might imagine errors caused by a lens with a 'rough' surface - pure waves come in and a more-or-less focused beam comes out.
How the eye focuses light versus how it 'should' focus light.
