A New Optical-Geometrical Illusion

open access: yesPerception, 2007
We 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)

Anomalous Mirror Symmetry Generated by Optical Illusion

open access: yesSymmetry, 2016
This paper introduces a new concept of mirror symmetry, called “anomalous mirror symmetry”, which is physically impossible but can be perceived by human vision systems because of optical illusion. This symmetry is characterized geometrically and a method

Optical illusion effects created by using metamaterials

open access: yes, 2009
We show that a general form of illusion can be achieved using the technique of transformation optics so that an arbitrary object appears like some other object of our choice.

On the interpretation of optical illusions

Kybernetik, 1973
If excited by stimuli adjacent in space and time, the optical system frequently perceives illusions in the form of apparent movements. These effects may be attributed to the dynamic properties of the retinal nerve nets. On the basis of a specific psychophysical experiment the mechanism underlying the generation of optical illusions is interpreted by ...

Illusion optics

Frontiers of Physics in China, 2010
The technique of "transformation optics" establishes a correspondence between coordinate transformation and material constitutive parameters. Most of the transformation optics mappings give metamaterials that have graded positive refractive indices that can steer light in curves defined by the coordinate transformation.
