keygen amazing adventures lost tomb Researchers at the cara crack aplikasi di android (SUTD) are constantly coming up with new discoveries and 3D printing applications, from from dust crack only download to pro tools hd 9.0.5 crack mac os lion. Now scientists at SUTD have used 3D printing to develop something that not only looks really cool, but can also be used to deter counterfeiting.
eassos recovery free 3.3.1 keygen The device, which the scientists call “holographic color prints,” creates images that appear as a regular color print under white light. Under red, green or blue laser illumination, the device projects up to three different holograms. It is capable of modulating both the phase and the amplitude of light. The research is documented in a paper entitled “descargar plantas contra zombies completo con crack.”
easy file sharing web server 6.0 crack Conventional optical security devices provide authentication by manipulating a specific property of light to produce a distinctive optical signature. Microscopic color prints modulate the amplitude and holograms modulate the phase of light, but the researchers believe that this structure can be easily imitated. So they designed a pixel that overlays a structural color element onto a phase plate to control both the phase and amplitude of light. They then arrayed the pixels into monolithic prints, with each pixel strategically arranged on a plane. Nanostructured posts with different heights were used as structural colored filters to modulate the amplitude of light.

They then used a nanoscale 3D printer to create a holoscopic print of painter Luigi Russolo’s 1910 painting “Perfume.” The color print is visible under ambient white light. Different thicknesses of polymerized cuboid were used to modulate the phase plates and form three multiplexed holograms, projected as a red thumbprint, a green key, and blue letters that read “SECURITY.” The images were embedded within the print.

Information in the prints is encoded only in the surface relief of a single polymeric material, so nanoscale 3D printing could then be used to mass manufacture customized masters by nanoimprint lithography.
