Negative Reflecting Meta-Mirrors

Real Mirrors Reflecting Virtual Worlds

This paper introduces the idea of using real mirrors in combination with rear-projection systems for the purpose of interacting with and navigating through the displayed information. Subsequently a derived application is described. For this, we use a hand-held planar mirror and address two fundamental problems of applying head tracking with rear-projection planes: the limited viewing volume of ...

Modeling of phase volume diffractive gratings, part 2: reflecting sinusoidal uniform gratings, Bragg mirrors

A detailed model of diffraction of plane and Gaussian beams on plane uniform phase Bragg gratings based on a Kogelnik's theory of coupled waves is presented. The model describes reflecting gratings (Bragg mirrors) with arbitrary orientation in a plane-parallel plate having no material losses. It takes into account spectral width and angular divergence of laser beams. The results of modeling are...

Smoke and Mirrors: Reflecting Files at a Geographically Remote Location Without Loss of Performance

The Smoke and Mirrors File System (SMFS) mirrors files at geographically remote datacenter locations with negligible impact on file system performance at the primary site, and minimal degradation as a function of link latency. It accomplishes this goal using wide-area links that run at extremely high speeds, but have long round-trip-time latencies—a combination of properties that poses problems...

The reflecting team: dialogue and meta-dialogue in clinical work.

A "stuck" system, that is, a family with a problem, needs new ideas in order to broaden its perspectives and its contextual premises. In this approach, a team behind a one-way screen watches and listens to an interviewer's conversation with the family members. The interviewer, with the permission of the family, then asks the team members about their perceptions of what went on in the interview....
