Contents (click to jump to a section)


This document was taken from the internet, but in fact seems to be taken from the inside cover of Wandell, Brian A. (1995) Foundations of vision (Sunderland, Mass. : Sinauer Associates), with some additions of my own.

I have not myself checked most of the facts listed here.

N.B. "X^2" means X raised to the second power i.e. X squared. And "X^-3" means X raised to the power -3 i.e. 1 divided by X cubed.
A "mu" means a micron i.e. 10^-6 of a metre (one thousandth of a millimetre).
