Coherent arrays of glass capillaries filled with liquid scintillator offer interesting possibilities in high resolution particle tracking. We describe the preparation and filling of capillary targets with 20 and 120-mu-m diameter lightguides, as well as the performance of capillary targets in a 5 GeV test beam exposure. Considerations are given concerning choice and optimization of solvents with high refractive index and fluorescence dyes. Furthermore results of systematic studies of liquid scintillators in beam tests are reported.

Direct Reconstruction of Pharmacokinetic-Rate Images of Optical Fluorophores From NIR Measurements Alacam, Burak; Yazici, Birsen (Institute of Electrical and Electronics Engineers (IEEE), 2009-09-01) In this paper, we present a new method to form pharmacokinetic-rate images of optical fluorophores directly from near infra-red (NIR) boundary measurements. We first derive a mapping from spatially resolved pharmacokinetic rates to NIR boundary measurements by combining compartmental modeling with a diffusion based NIR photon propagation model. We express this mapping as a state-space equation. Next, we introduce a spatio-temporal prior model for the pharmacokinetic-rate images and combine it with the state...
Symmetrical and decoupled nickel microgyroscope on insulating substrate Alper, Se; Akın, Tayfun (Elsevier BV, 2004-09-21) This paper presents a symmetrical and decoupled surface micromachined gyroscope fabricated by electroforming thick nickel on a glass substrate. The symmetric structure allows matched resonant frequencies for the drive and sense vibration modes for improved sensitivity, while the decoupled drive and sense oscillation modes prevents unstable operation due to mechanical coupling, resulting in a low zero-rate output drift. The use of a glass substrate instead of a silicon substrate reduces noise due to the para...
Single and dual band quantum well infrared photodetector focal plane arrays on inp substrates Eker, Süleyman Umut; Beşikci, Cengiz; Department of Electrical and Electronics Engineering (2010) Excellent uniformity and mature material properties of Quantum Well Infrared Photodetectors (QWIPs) have allowed the realization of large format, low cost staring focal plane arrays (FPAs) in various thermal imaging bands. AlGaAs/InGaAs and AlGaAs/GaAs materials systems have been the standard systems for the construction of mid-wavelength infrared (MWIR) and long-wavelength (LWIR) QWIPs. However AlGaAs/GaAs QWIP FPAs suffer from low quantum and conversion efficiencies under high frame rate (low integration ...
Sensor Fusion of a Camera and 2D LIDAR for Lane Detection Schmidt, Klaus Verner (null; 2019-04-26) This paper presents a novel lane detection algorithm based on fusion of camera and 2D LIDAR data. On the one hand, objects on the road are detected via 2D LIDAR. On the other hand, binary bird’s eye view (BEV) images are acquired from the camera data and the locations of objects detected by LIDAR are estimated on the BEV image. In order to remove the noise generated by objects on the BEV, a modified BEV image is obtained, where pixels occluded by the detected objects are turned into background pixels. Then,...
Ensemble monte carlo simulation of quantum well infrared photodetectors, and inp based long wavelength quantum well infrared photodetectors for thermal imaging Cellek, Oray Orkun; Beşikci, Cengiz; Department of Electrical and Electronics Engineering (2006) Quantum well infrared photodetectors (QWIP) utilize quantum wells of large bandgap materials to detect infrared radiation. When compared to conventional low bandgap LWIR photodetectors, the QWIP technology offers largest format thermal imagers with much better uniformity. The theoretical part of this study includes the development of a QWIP ensemble Monte Carlo simulator. Capture paths of electrons to quantum wells are simulated in detail. For standard AlGaAs/GaAs QWIPs, at medium and high E-fields L valley...
