Visualizing Objects with Mirrors
We present an automatic camera and mirrors placement method for visualizing 3D scenes such that complete and nonredundant visibility is guaranteed, as well as highest image resolution. We provide algorithms and geometries for optimal object-independent mirrors and viewpoint placement for all objects in a specific class. We also briefly consider object-dependent algorithmic problems, where mirro...
متن کاملStereo with Mirrors *
I n this paper, we propose the use of mirrors and a single camera for computational stereo. W h e n compared to conventional stereo systems that use two cameras, our method has a number of significant advantages such as wide field of view, single viewpoint projection, identical camera parameters and ease of calibration. W e propose four stereo systems that use a single camera pointed towards pl...
متن کاملTrapping Light With Mirrors
We show that, given finitely many line-segment mirrors in the plane, that do not touch, and an arbitrary point source of light, if all angles made by lines parallel to mirrors are rational multiples of π, then all but countably many emitted light beams escape. This result is shown to imply that, for a given point source of light, a randomly chosen configuration of finitely many nontouching line...
متن کاملNarrowing light rays with mirrors
Pach raised the question of whether a match lit in a nite forest of disjoint circular mirror trees necessarily sends light to innnity CFG90]. In other words, can one trap light rays from a point source with such mirrors? This remains an unsolved problem. We pose related mirror trapping questions. Can one trap light with arbitrarily curved mirrors? Here the answer is yes. Can one trap light with...
متن کاملCavity QED with atomic mirrors
A promising approach to merge atomic systems with scalable photonics has emerged recently, which consists of trapping cold atoms near tapered nanofibers. Here, we describe a novel technique to achieve strong, coherent coupling between a single atom and photon in such a system. Our approach makes use of collective enhancement effects, which allow a lattice of atoms to form a high-finesse cavity ...
