Holographic Color Prints Combine Phase and Amplitude Control of Light for Better Optical Security
Holographic Color Prints Combine Phase and Amplitude Control of Light for Better Optical Security
A new optical anticounterfeiting device, called “holographic color prints” by its developers, provides a dual function to increase security and deter counterfeiting. The device creates images that appear as a regular color print under white light. But under red, green, or blue laser illumination, the device can project up to three different holograms.

Strain Engineering Produces Highly Stable, Narrow Bandwidth Light From Individual QDs
Strain Engineering Produces Highly Stable, Narrow Bandwidth Light From Individual QDs
New research suggests that asymmetrically strained colloidal quantum dots (QDs) can provide stable, blink-free light emission comparable to the light produced by QDs made through more complex processes. The strained QDs were found to emit spectrally narrow light with a highly stable intensity and a nonfluctuating emission energy.

New Additive Manufacturing Method Uses Light to Prevent Resin From Curing Against Vat
New Additive Manufacturing Method Uses Light to Prevent Resin From Curing Against Vat
A new approach to 3D printing uses two-color irradiation of resin formulations that contain both a photoinitiator and a photoinhibitor to perform vat-printing up to 100 times faster than conventional 3D printing processes. The new technique allows control over where the resin hardens and where it stays fluid, enabling the resin to solidify into more complex patterns.
