We describe a femtosecond photoelectron and photoion spectroscopy setup using a simple, novel way to produce a vacuum ultraviolet (VUV) probe pulse. We isolate the femtosecond VUV pulse from a high harmonic continuum by using the bandpass characteristics o ...
We investigate the effect of spatial dispersion phenomenon on the performance of graphene-based plasmonic devices at terahertz (THz). For this purpose, two different components, namely a phase shifter and a low-pass filter, are taken from the literature, i ...
For dynamic samples and/or for simple ease-of-use experiments, single-image phase contrast tomography is a very effective method for the 3D visualization of materials which would otherwise be indiscernible in attenuation based x-ray imaging. With binary sa ...
A PbS:Hg quantum dots-sensitized solar cell (QDSC) combined with a dye-sensitized solar cell (DSC) to harvest panchromatic solar spectrum from the visible light to the near IR is demonstrated. We use the filter to split the solar energy and access the tota ...
Within this thesis two experiments will be described. In the first experiment a velocity filter was used to obtain a beam of polar molecules (ND3) with a translational temperature of less than 5K. For the first time the dynamics of individual rotational st ...
The bacterial inactivation of Escherichia coli on Cu/CuO-polyester surfaces prepared by direct current magnetron sputtering was investigated in the dark and under actinic light (360nm
In a previous study, we showed that visual spatiotemporal processing deteriorates with healthy ageing (Roinishvili et al, 2011, Vision Research, 51(4):417-23). Here, we used backward masking to investigate the underlying mechanisms. First, thirty-three old ...
We present an accurate, efficient, and robust pose estimation system based on infrared LEDs. They are mounted on a target object and are observed by a camera that is equipped with an infrared-pass filter. The correspondences between LEDs and image detectio ...
In this paper we present a method for fusing optical flow and inertial measurements. To this end, we derive a novel visual error term which is better suited than the standard continuous epipolar constraint for extracting the information contained in the op ...
The electrical detection of surface spin polarization in Indium Phosphide (InP) is demonstrated. Using a planar four-terminal architecture on top of semi-insulating Fe: InP (001) wafers, optical orientation is separated from electrical detection. Spin filt ...
