A laboratory test setup is built to transfer and actively stabilize an ultrastable signal, obtained from a laser with sub-Hz linewidth, trough a 5 km long fiber link. The fiber noise is measured and compensated via a feedback loop acting on an AOM that can change the frequency (and therefore the phase) …

Resonance-enhanced laser-induced breakdown spectroscopy was used to increase the elemental sensitivity of laser-induced breakdown spectroscopy. In resonance-enhanced laser-induced breakdown spectroscopy, two lasers are used. The first laser creates a plasma, and the second laser re excites the most …

To compare comfort‐related outcomes when wearing rigid gas permeable (RGP) contact lenses made of two different materials and using two cleaning regimes. In a double‐masked lens material cross‐over study, subjects (n = 28 who completed the study) were refitted with new lenses made from (A) Boston XO …

In an previous research project a new type of greenhouse with an integrated concentrated photovoltaic system (CPV) was developed which has an integrated filter for reflecting the near infrared radiation (NIR) to the greenhouse and exploiting this radiation in a solar energy system. The performance of …

In a double-masked randomized controlled crossover study we investigated both the retinal responses to straylight, and the effects of lens cleaners on straylight values, in two different RGP contact lens materials. Methods: Thirty patients (20-59 years) wearing RGP lenses were refitted with new lenses …

In this paper the design and development of a new type of greenhouse with an integrated filter for reflecting near infrared radiation (NIR) and a solar energy delivery system is described. Especially the optical parts as the spectral selective film, the properties of the circular reflector and the efficiencies …
