A New Optical-Geometrical Illusion
Perception, 2007We describe and attempt to explain a new and unusual optical-geometrical illusion with three levels of distortion. The illusory figure is made up of three juxtaposed bands of the same width, which, when appropriately juxtaposed, appear to be of different widths. We hypothesised that the effect would depend on the combined action of various factors: (i)

Geometrical Optical Illusionists
Perception, 2014Geometrical optical illusions were given this title by Oppel in 1855. Variants on such small distortions of visual space were illustrated thereafter, many of which bear the names of those who first described them. Some original forms of the geometrical optical illusions are shown together with ‘perceptual portraits’ of those who described them.

, 2012 The ability to model the propagation of light is a vital element of understanding any display technology.Whether it is a liquid crystal display backlight or a digital cinema projector, the principles of optical propagation still apply.

Abstract The theory of geometrical optics as presented here is associated with rays that propagate at small angles where the sine of the angle can be replaced by the angle in radians. This is called the paraxial theory and it fails to describe the actual performance of an optical system.
