Photoswitch Chemistry Creates 3D Shapes From Light

Facebook Twitter LinkedIn Email Comments
A novel technology uses a special class of photoactivatable molecules and digital light processing (DLP) to construct light shapes into animated structures that have volume and are viewable from 360 degrees. The technology is not a hologram, and differs from 3D movies or 3D computer design. The set-up for the 3D Light PAD includes this UV projector as well as a visible projector. They project patterns of light into a chamber of photoactivatable dye. Wherever the UV light intersects with the green light it generates a 3D image inside the chamber.
