Holographic color printing for optical security Date: January 8, 2019 Source: Singapore University of Technology and Design Summary: Researchers have invented a new type of anti-counterfeiting ...

Each pixel acts as a speed bump (phase control) and road blocks (amplitude control) for light. The dual-function of holographic colour printing increases security and deters counterfeiting.

The SUTD research team developed a new type of anti-counterfeiting device, i.e. holographic colour printing, which modulates both the phase and amplitude of light. Holographic colour printing displays ...

Researchers are creating a new approach to reconstruct 3-D full-color holographic images by using just one layer of nanoscale metallic film. This work has a huge potential to change our daily ...
