BBCより。グラスゴーの科学者が２つのカメラではなく１つで３Ｄ写真を取れる技術を開発したということだ。ポイントはライティング。ライティングによる光とその反射を利用して2次元の画像が3次元に変換できるという仕組みのようだ。

Glasgow scientists create single-pixel camera for 3D images
A projector displays patterned light on the face on a mannequin. These patterns are used to produce a 2D image. A 3D image is then formed using a technique called “shape from shade”
Scientists in Glasgow have discovered a low-cost way to create 3D images.
Their system uses detectors which have a single pixel to sense light instead of the millions of pixels used in the imaging sensors of digital cameras.
The detectors can “see” frequencies beyond visible light, which researchers say could open up new uses for 3D imaging in medicine and geography.
They said the single-pixel detectors cost “a few pounds” compared to current systems, which cost “thousands”.
It is hoped that the system’s ability to senses wavelengths far beyond the capability of digital cameras and its low cost, could make it a valuable tool for a wide range of industries.
Researchers said possible uses could range from locating oil to helping doctors find tumours.
Crossword patterns
Prof Miles Padgett led the team at University of Glasgow’s School of Physics and Astronomy, which developed the technique.
He said: “Single-pixel detectors in four different locations are used to detect light from a data projector, which illuminates objects with a rapidly-shifting sequence of black-and-white patterns similar to crossword puzzles.
