This paper presents a driving circuitry system for high-resolution, pixelated-LED automotive headlamps. The consists of an array pixel drivers, and row/column driver suitable active-matrix configuration with the individual dimming control capabilities on each pixelated-LED. An asynchronous serial communication protocol is introduced to minimize number data transmission interface signals between...

On-chip multi-dimensional detection systems integrating pixelated polarization and spectral filter arrays are the latest trend in optical instruments, showing broad application potential for diagnostic medical imaging remote sensing. However, thin-film or microstructure-based typically have a trade-off between dimension, efficiency, resolution. Here, we demonstrate novel on-chip integrated cons...

The vignetting effect reduces the performance of a multi-input multi-output (MIMO) wireless communication system. A gradual fall-off in illumination at the edges of a received image will occur due to the vignetting effect. In order to improve the performance of the pixelated MIMO optical wireless communication system the Non-DCBiased spatial orthogonal frequency division multiplexing (OFDM) is ...

In pixelated CdZnTe detectors, multiple interaction gamma-ray events are critical because they permit Compton imaging. However, in large-volume CdZnTe crystals, the depth of multiple interaction events is often poorly reconstructed due to significant nonuniformity of electron drift velocity while the depth of single interaction events can be accurately reconstructed using signal ratios. The non...

We have developed a position-sensitive scintillation camera with a large area absorber for use as an advanced Compton gamma-ray camera. At first we tested GSO(Ce) crystals. We compared light output from the GSO(Ce) crystals under various conditions: the method of surface polishing, the concentration of Ce, and co-doping Zr. As a result, we chose the GSO(Ce) crystals doped with only 0.5 mol% Ce,...

As feature size is much smaller than the wavelength of illumination source of lithography equipments, resolution enhancement technology (RET) has been increasingly relied upon to minimize image distortions. In advanced process nodes, pixelated mask becomes essential for RET to achieve an acceptable resolution. In this paper, we investigate the problem of pixelated binary mask design in a partia...

Animals, such as Savannah sparrows and North American monarch butterflies, are able to obtain compass information from skylight polarization patterns to help them navigate effectively and robustly. Inspired by excellent navigation ability of animals, this paper proposes a novel image-based polarized light compass, which has the advantages of having a small size and being light weight. Firstly, ...

Department of Physics of Molecular Imaging Systems, Institute for Experimental Molecular Imaging, RWTH Aachen University, Aachen, Germany Conventional positioning algorithms in PET assume a photon interaction and complete energy deposition in one detector element (single-hit). However, there is a high probability that a photon interacts within a crystal element via Compton scattering but is abs...
