Doel: Evaluatie van de sensitiviteit en specificiteit van Spectral Domain Optical Coherence Tomography (SD-OCT) ten opzichte van fluorescentie angiografie (FAG) in het aantonen van choroïdale neovascularisatie (CNV) bij leeftijd gerelateerde maculadegeneratie (LMD). Methode: Resultaten van wetenschappelijke …

Doelstelling De ziekte van Alzheimer is een degeneratieve neurologische aandoening die zorgt voor degeneratie van zenuwcellen in de hersenen en mogelijk ook in de retinale zenuwvezellaag. Mogelijk is er een verband tussen de verdunning van de retinale zenuwvezellaag en de ziekte van Alzheimer. Materiaal …

This thesis describes how the abundance of CO2 a ects the porosity of H2O:CO2 ice mixtures deposited at di erent growth temperatures ranging from 30 - 70 K. The mixing ratios of the used ice samples H2O:CO2 = 10:1, 4:1 and 2:1 are of astrophysical relevance. Laser optical interference is used to monitor …

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) …

We present a novel method to achieve light trapping in thin film silicon solar cells. Unlike the commonly used surface textures, such as Asahi U-type TCO, that rely on light scattering phenomena, we employ embossed periodically arranged micro-pyramidal structures with feature sizes much larger than the …

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 …

Single Fiber Reflectance spectroscopy (SFR) can be used to determine tissue optical properties such as scattering and absorption. The SFR technique employs a semi-empirical modal, which contains a parameter that is dependent on the fiber numerical aperture, NA . However, the NA is a wavelength dependent …

Rational exportations warrant a multitude of sophisticated homework done in advance in an enterprise's homeland as prerequisite before the conscientious companies could embark on their discrepant exportation efforts. This report expounded hereinafter aims to furnish the author's internship assignment …

Laser Doppler perfusion imaging (LDPI) has been proven to be a useful tool in predicting the burn wound outcome in an early stage. A major disadvantage of scanning beam LDPI devices is their slow scanning speed, leading to patient discomfort and imaging artifacts. We have developed the Twente Optical …
