We have developed a new type of transparent volumetric three-dimensional (3D) image display in which a thin photopolymer sheet containing Lanthanide(III) complexes is used as a rotational screen. The Lanthanide(III) complexes used in our system are Eu(TTA)(3) Phen, designed for achieving red luminescence (615nm) for an excitation light of 395 nm. An arbitrary luminous point (voxel) is identified by controlling the excitation laser beam direction in synchronization with the photopolymer sheet rotation. The full colorization of the proposed volumetric 3D image display can be realized by using, for example, Eu(TTA)(3) Phen, Tb(ACAC)(3) Phen, and Coumarin 337, simultaneously.
This article introduces the concept of an optical full-mesh network for achieving ultra-low-latency transmission of diverse and large-capacity content in ultra-realistic services and the technologies underlying this network. It also introduces a demonstration of 8K uncompressed video transmission in a largecapacity optical transmission system as an embodiment of the optical full-mesh network concept.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
