Transflective holographic film for head worn display

Jürgen Brugger, Christophe Moser, Eric Tremblay, Victor Javier Cadarso Busto, Jonas Grossenbacher

A display panel assembly comprises a transflective holographic screen, i.e., a transparent screen that reflects light from a projection system, comprising at least a volume hologram, a first protective element and a second protective element, each arranged ...

Complex pattern projection through a multimode fiber

Demetri Psaltis, Christophe Moser, Damien Claude-Marie Loterie, Salma Farahi

Wavefront shaping through multimode fibers has many interesting applications, such as micromanipulation and endoscopy, where the small diameter of fibers is an advantage in terms of miniaturization. However, pattern projection can suffer from deleterious i ...

Time- and Space-Efficient Sliding Window Top-k Query Processing

Karl Aberer, Kresimir Pripuzic

A sliding window top-k (top-k/w) query monitors incoming data stream objects within a sliding window of size w to identify the k highest-ranked objects with respect to a given scoring function over time. Processing of such queries is challenging because, e ...

Search for the process e(+)e(-) -> J/psi X(1835) at root s approximate to 10.6 GeV

Jian Wang, Olivier Schneider, Chao Wang, Tagir Aushev, Ji Hyun Kim, Donghyun Kim, Dipanwita Dutta

We report the results of a search for the X(1835) state in the process e(+)e(-) -> J/psi X(1835) using a data sample of 672 fb(-1) collected with the Belle detector at and near the Upsilon(4S) resonance at the KEKB asymmetric-energy e(+)e(-) collider. No s ...

CAMEA: Technical Solutions

CAMEA is a new instrument concept so it is possible that the construction could or maintenance of the instrument would be hampered by technical details. In order to prevent this a technical predesign have been performed. This is not a final technical solut ...

ESS Instrument Construction Proposal CAMEA

Henrik Moodysson Rønnow, Paul Gregory Freeman

We propose the construction of a highly innovative spectrometer – CAMEA – offering Continuous Angular and Multiple Energy Analysis. Combining indirect time-of flight with multiple consecutive analyser arrays, this instrument will provide massive flux on th ...

CAMEA: Simulations and Kinematic Calculations

During the design of CAMEA extensive simulations and cinematic calculations were performed to explore the waste parameter space. These have led to a far better understanding of the instrument performance as well as new ideas to improve the instrument. Many ...

Analytical Calculations for CAMEA

CAMEA is a novel instrument concept, thus the performance has not been explored. Furthermore it is a complex instrument using many analyser arrays in a wide angular range. The performance of the instrument has been studied by use of three approaches: McSta ...

Jaggies as aliasing or reconstruction phenomena: a tutorial

Roger Hersch, Isaac Amidror

Jaggies (staircasing effects) along slanted lines or curved edges are omnipresent in digital imaging. They are so widespread in digital display devices that very often they are associated with the modern "computerized" world (and sometimes even intentional ...

Computationally efficient background subtraction in the light field domain

Martin Vetterli, Mahdad Hosseini Kamal, Alireza Ghasemi

Since the invention of first camera, people have always thought of new ways to capture moments. With the advent of digital photography, not only imaging systems have progressed, but also technology provides new user experience. The recently introduced ligh ...
