SUTD researchers have used nanotechnology to create a unique print that displays a glasses-free 3D image under ordinary white light. The appearance of the image changes as the print is viewed from varying angles. The print is called a ‘light field print’ for its unique design and appearance as compared to conventional 2D images.

Wouldn’t it be amazing if printed images can look three-dimensional (3D)? Unfortunately, conventional prints like photographs display two-dimensional (2D) images with a fixed appearance as they contain only intensity and colour information. These prints are unable to display a 3D image because they lack directional control of light rays, hence resulting in the loss of depth information.
