SINGAPORE, Jan. 10, 2019 — A new optical anticounterfeiting device, called “holographic color prints” by its developers at the Singapore University of Technology and Design (SUTD), 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. It is able to modulate both the phase and amplitude of light. Enhanced optical security provided by a six-color holographic color print.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookLaser Safety: Important Considerations: Laser safety is nothing to scoff at; lasers can be hazardous.
