Holography is a powerful technique of photography of a light field without a lens for 3D imaging and display. Now, scientists at the Max-Planck Institute of Quantum Optics are moving holography ...

As object identification and three-dimensional (3D) reconstruction techniques become essential in various reverse engineering, artificial intelligence, medical diagnosis, and industrial production ...

Toyohashi University of Technology discovered that when people judge the thickness of an object, objects with glass-like transparent optical properties are perceived to be flatter than they actually ...

Three-dimensional objects and textiles in the collection relate to women in medicine and Woman’s Med, and to Hahnemann University and homeopathy. Three-dimensional object types include surgical and ...

For decades mathematicians have searched for a specific pair of surfaces that can’t be transformed into each other in four-dimensional space. Now they’ve found them. In geometry and the closely ...

The basic lantern object is made by cutting a polymer sheet into a diamond-like parallelogram shape, then cutting a row of parallel lines across the center of each sheet. This creates a row of ...

The idea that a hidden fourth dimension could be woven into everyday reality is no longer just a science‑fiction trope. Leading theorists now argue that extra dimensions are not only compatible with ...

Scheme illustration of object identification and all-optical 3D reconstruction system. (a) A contour surface image of the object can be obtained in a single processing of the system. (b) High-contrast ...
