Changes in peripheral ocular aberrations with accommodation: pilot study
Sandra Franco, Jessica Gomes, Kishor Sapkota
Centre of Physics, University of Minho, Portugal
The study of the interaction between ocular aberrations and accommodation has been the subject of several studies during the last years. However, these studies have not evaluated the impact of accommodation on peripheral aberrations.
The ocular aberrations were measured, with an in-house Hartmann-Shack aberrometer in five different field locations (central, nasal, temporal, superior and inferior). The results were analysed in terms of primary and secondary spherical aberration, RMS,and spherical equivalent, M. The results indicated that system can be feasible to measure the peripheral ocular aberrations during accommodation changes.

Experimental Mueller matrix polarimetry with full Poincaré beams and a CCD camera

Full Poincaré beams present all possible polarization states across their transverse section. By using a simple polarization analyzer and a CCD camera, a polarization map of the beam cross section can be obtained. This polarization map is modified when a sample is inserted before the polarization state analyzer. An overdetermined system of linear equations can be written relating these two polarization maps. The Mueller matrix of the sample is obtained as optimum solution of such a system. Some experimental results will be presented to check the performance of the proposed polarimetric method.

Visible light backscatter: Fusing sensing with illumination
Andreas Peter Weiss, Kushal Madane, Christian Fragner, Andreas Kröpfl, Stefan Schantl, Franz Peter Wenzl
JOANNEUM RESEARCH ForschungsgesmbH, Austria
Light-emitting diode (LED) based luminaires allow to provide also functionalities beyond illumination. Examples comprise communication, localization and, most recently, backscattered visible light sensing. Here we demonstrate and discuss system designs for functional lighting, which enable tunable artificial illumination (dimming, variation of color temperature) that allows to perform sensing tasks (like identification and velocity determination of moving objects) in parallel, and outline the prospects of tailored optical surfaces for future advancements of visible light backscatter technologies.

This research aims to develop asphalt mixtures with new capabilities with photocatalytic, superhydrophobic, and self-cleaning capabilities. Different solutions were prepared combining nano-TiO2 and micro-PTFE on water, and ethyl alcohol and dimethyl ketone with different concentrations. The solutions were sprayed over the asphalt mixtures and the new capabilities were evaluated via decolourization of Rhodamine B dye aqueous solution under simulated solar irradiation and Water Contact Angle measurements. Among the combinations analysed, the best solution was TiO2 PTFE with ethyl alcohol (8 g/L).

Transient optical simulation by coupling finite elements, elastic multibody systems and ray tracing
Luzia Hahn, Fabian Matter, Peter Eberhard
Institute of Engineering and Computational Mechanics, University of Stuttgart, Germany
Integral optical system simulation allows the behavior prediction for complex optical systems. This paper presents a method for holistic transient dynamical-thermoelastic-optical system simulation. Both thermoelastic as well as dynamical effects are taken into account in a gradient index ray tracing procedure.
