In this study, we introduce a wide spectral range (200-2500 nm) imaging system with a 250 μm minimum spatial resolution, which can be freely modified for a wide range of resolutions and measurement geometries. The system has been tested for reflectance and luminescence measurements, but can also be customized for transmittance measurements. This study includes the performance results of the dev...

This paper reports on efforts to enhance the photovoltaic performance of textured silicon solar cells through the application of a layer of Eu-doped silicate phosphor with particles of various dimensions using the spin-on film technique. We examined the surface profile and dimensions of the Eu-doped phosphors in the silicate layer using optical microscopy with J-image software. Optical reflecta...

Snow and ice on roads often lead to increased rolling resistance that makes less accessible attractive for cyclists. Introducing a minimum requirement in winter maintenance of cycleways may increase the attractiveness cycling. To control level, an objective measurement method is needed. This article presents new measuring cyclists by using instrumented bicycle. The utilizes measurements pedalin...
