Design of a light confining concentrator for a solar photochemical reactor and upper bound to the method
Marilyne Andersen, Boris Clément Karamata
Optical concentration obtained by light confinement bears unique features that can increase the efficiency of a photochemical reactor. A suitable implementation of this method for a solar reactor is a series of parallel tubular receivers sealed in a slab-s ...
Spie-Int Soc Optical Engineering2016Concept, Design and Performance of a Shape Variable Mashrabiya as a Shading and Daylighting System for Arid Climates
Marilyne Andersen, Boris Clément Karamata
The design of a solar protection system that can minimize solar gains while maximizing daylight and view to the outside is particularly challenging in arid climates, such as in the Middle-East, where sand, wind and corrosion impose specific constraints. We ...
CEPT University Ahmedabad2014Origin and nature of measurement bias in catadioptric parallel goniophotometers
Marilyne Andersen, Boris Clément Karamata
We briefly categorize and compare parallel goniophotometers, which are instruments capable of simultaneously measuring the far-field distribution of light scattered by a surface or emitted by a source over a large solid angle. Little is known about the acc ...
2014Stationary solar concentrator delivering beyond the étendue law with homogeneous illumination
Marilyne Andersen, Boris Clément Karamata
We describe a concept for a novel stationary solar concentrator that relies on a new self-adaptive optical valve, non-imaging optics and the integrating sphere principle. Our analytical model reveals that this unique combination theoretically allows reachi ...
2014Revisiting parallel catadioptric goniophotometers
Marilyne Andersen, Boris Clément Karamata
A thorough knowledge of the angular distribution of light scattered by an illuminated surface under different angles is essential in numerous industrial and research applications. Traditionally, the angular distribution of a reflected or transmitted light ...
Spie-Int Soc Optical Engineering2013A review and analysis of parallel goniophotometry
Marilyne Andersen, Boris Clément Karamata
A reliable computer simulation of natural and artificial lighting of an indoor environment requires the thorough knowledge of the angular intensity distribution of light scattered or emitted by the various objects involved such as the illuminated surfaces, ...
2013Limits and artefacts of reflective imaging goniophotometers for complex solar façade systems
Marilyne Andersen, Boris Clément Karamata
The design of systems for solar light collection, modulation and/or distribution requires a thorough knowledge of their optical properties. The angular distribution of the scattered incident light flux, described by the Bidirectional Scattering Distributio ...
2012NOMAD - Network of Optimization Modalities in Architectural Design
Marilyne Andersen, Boris Clément Karamata, Loïc Vivien Fumeaux, Dan-Alexis Bolomey
Two pairs of identical experimentation modules are being developed within the framework of a collaborative initiative named NOMAD – Network of Optimization Modalities in Architectural Design - between the Interdisciplinary Laboratory of Performance-Integra ...
2011Speckle statistics in optical coherence tomography
Theo Lasser, Boris Clément Karamata, Kai Hassler, Markus Laubscher
The two previously reported calculations of the amplitude distribution of speckles in optical coherence tomography, each based on a different mathematical formulation, yield different results. We show that a modification of an initial assumption in one of ...
2005Multiple scattering in optical coherence tomography. I. Investigation and modeling
Theo Lasser, Boris Clément Karamata, Marcel Leutenegger, Stéphane Bourquin, Markus Laubscher
We present a new model of optical coherence tomography (OCT) taking into account multiple scattering. A theoretical analysis and experimental investigation reveals that in OCT, despite multiple scattering, the field backscattered from the sample is general ...
