A three-dimensional thermal cloak can conceal objects from heat, paving the way toward new military stealth technologies.

On an infrared camera, a warm object normally stands out clearly against its cooler surroundings. Researchers at the ...

Scientists have developed the world’s first true three-dimensional thermal cloak, a device that can hide objects from heat ...

Holograms that offer a three-dimensional (3D) view of objects provide a level of detail that is unattainable by regular two-dimensional (2D) images. Due to their ability to offer a realistic and ...

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 ...

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 ...
