Holograms, 3-D said to be on verge of new era
Forum explores next-generation display technology
CAMBRIDGE -- A couple of decades ago, holograms seemed futuristic and cool, a next-generation visual medium. Then, they began to seem more fusty than fantastic, commonly used as anti-counterfeit watermarks. But today, with the resurgence of interest in 3-D in movies and the continued evolution of cameras and computational power, holography is poised to enter its second act, supporters say. This week, 150 artists, scientists, and engineers gather at the Massachusetts Institute of Technology for an international conference devoted to holograms.
