Illusion optics: The optical transformation of an object into another object

, 2009
We propose to use transformation optics to generate a general illusion such that an arbitrary object appears to be like some other object of our choice.

Rectangularity Is Stronger Than Symmetry in Interpreting 2D Pictures as 3D Objects

Frontiers in Human Neuroscience, 2022
It is known that the human brain has a strong preference for rectangularity in interpreting pictures as 3D shapes. Symmetry is also considered to be a factor that the human vision system places high priority on when perceiving 3D objects.

State anxiety influences P300 and P600 event-related potentials over parietal regions in the hollow-mask illusion experiment

Personality Neuroscience, 2021
The hollow-mask illusion is an optical illusion where a concave face is perceived as convex. It has been demonstrated that individuals with schizophrenia and anxiety are less susceptible to the illusion than controls. Previous research has shown that the

Cloaking and imaging at the same time

, 2012
In this letter, we propose a conceptual device to perform subwavelength imaging with positive refraction. The key to this proposal is that a drain is no longer a must for some cases.

Réflexion sur un phénomène optique qui inspire des philosophes [PDF]

Svět Literatury
The afterimage is generally considered to be an example of an optical illusion. But can it be more than just a trace of visual perception? The optical term nachbild, or afterimage, refers to this ghostly form of the visible, an image that is still there,

"Positive space (A new perspective for the application of the optical illusion art in advertising design)"

Journal of Architecture, Art & Humanistic Science, 2020
The Optical Art, known as Op-Art, is one of the artistic movements that emerged in the late twentieth century. It is characterized by a purely visual relationship between the recipient and the artistic work. It aims to change the visual perception of the

Observation of a classical cheshire cat in an optical interferometer

, 2015
A recent neutron interferometry experiment claims to demonstrate a paradoxical phenomena dubbed the "quantum Cheshire Cat" \cite{Denkmayr2014}. We have reproduced and extended these results with an equivalent optical interferometer.
