Method and light microscope with a plurality of arrays of photon-counting detector elements

Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic

A method for operating a light microscope comprises emitting and guiding a plurality of illumination light beams towards a specimen (6) to form a plurality of separated illumination light spots (2A, 2B, 2C, 2D) at the specimen; and guiding detection light ...

A smart luminaire in an office environment: impact on light distribution, user interactions and comfort

Jérôme Henri Kämpf

A smart luminaire able to change the direction of its light beam is installed in an office environment and compared to the available LEDs fixtures. Standard lighting measures are performed and a controlled user experiment is conducted, involving 22 subject ...

Light wavelength-dependent E. coli survival changes after simulated solar disinfection of secondary effluent

César Pulgarin, Sami Rtimi, Stefanos Giannakis

In this study, the photoreactivation and the modification of dark repair of E. coli in a simulated secondary effluent were investigated after initial irradiation under different conditions. The simulated solar exposure of the secondary wastewater was follo ...

A Novel Louver System for Increasing Daylight Usage in Buildings

Marilyne Andersen

Advanced daylighting systems can be effective in increasing light levels in building spaces and reducing energy consumption due to electric lighting. However, a recurring issue found in most existing daylighting systems is the necessity of coupling the lig ...

Visual Discomfort and Glare Rating Assessment of Integrated Daylighting and Electric Lighting Systems using HDR Imaging Techniques

Jean-Louis Scartezzini, Apiparn Borisuit

The combined integration of daylighting and electric lighting systems within buildings --also designated by the term “Green lighting”, which is a recent issue for the lighting research community-- allows achieving better lighting conditions for building oc ...

Light controlling light in an optical fibre: from very slow to faster-than-light speed

Luc Thévenaz, Kwang-Yong Song

We demonstrate a method to achieve an extremely wide and flexible external control of the group velocity of signals as they propagate along an optical fibre. This control is achieved by means of the gain and loss mechanisms of stimulated Brillouin scatteri ...
