A Treatise on Geometrical Optics [PDF]

open access: greenNature, 1887
THIS treatise is based on the conception of a beam of light as consisting of a system of rays, which obey the laws of reflexion and refraction. The transformations of such a system and the construction and properties of optical instruments are deduced, so far as the latter are capable of explanation from this point of view.

Geometric-optical illusions at isoluminance [PDF]

open access: yesVision Research, 2007
The idea of a largely segregated processing of color and form was initially supported by observations that geometric-optical illusions vanish under isoluminance. However, this finding is inconsistent with some psychophysical studies and also with physiological evidence showing that color and luminance are processed together by largely overlapping sets ...

Geometrical Optics in Absorbing Media [PDF]

open access: yesProceedings of the National Academy of Sciences, 1930
The problem of propagation of rays in a medium of variable absorption and refraction has acquired some practical importance in radiotelegraphy. The radio waves penetrate into the conducting and absorbing layer of the upper atmosphere(1) and describe there a certain path. The question was brought to my attention by Dr. B.

Geometrical optics and chessboard pebbling

open access: yesApplied Mathematics Letters, 2001
Since recently chessboard pebbling has been studied extensively in telecommunication. In this game, played on the infinite board \(\{(i,j)\}\) (\(i,j\) natural numbers), a set of pebbles are expanding toward infinity. In every step a cell \((i,j),\) containing pebble(s), is selected and the pebble moves over to the cells \((i,j+1)\) and \((i+1,j).\) A ...
