International conference on solid state sensors and Actuators (TRANSDUCERS)

作者： J.S. Haviland D.R. Krahn W.J. Johnson Honeywell Solid State Electronics Center Plymouth MN USA

A silicon-based integrated circuit array is demonstrated with a unique layout and process technique which allows a shortened development and fabrication time and reduced design and development costs for several types of monolithically integrated smart sensors. This array utilizes the same semi-custom techniques which have allowed similar development time improvements and cost reductions for digital gate arrays and analog tile arrays, but is designed specifically for use with monolithic silicon sensors and actuators. This array is known as the Linear IC/sensor Array, or LISA, and directly applies semi-custom design and processing techniques to monolithic smart sensor developments.< >

Information advantage is the key success factor in all conflicts. In a modern combat aircraft the amount of available information is continuously increasing with new and more sophisticated sensor systems. By incorporating an integrated mission recording system the vast amount of information captured in a modern combat aircraft is recorded. Evaluating this information, whether for aircraft development, pilot training or in combat, will maximize the experience from each night and enhance the efficiency of the following missions. All Lot 3 of the Swedish fighter JAS39 Gripen as well as the export versions will be equipped with a digital mission recording system. The system is called DiRECT and is used for video, audio and data recording on a direct access, solid-state memory.

Low-cost, disposable, SiO2/Si3N4 chemical field effect transistor (ChemFET) microsensors have been fabricated for pH measurements and adapted to biochemical applications by using polyvinyl alcohol (PVA) enzymatic layers deposited and patterned either by dip-coating, or spin-coating and photolithographic techniques. Both processes have been compared for the development and optimization of a creatinine-sensitive enzymatic field effect transistor (Creatinine-EnFET). Creatinine detection properties have been characterized in dialysate, demonstrating better properties for the spin-coated PVA enzymatic layers. Thus, creatinine sensitivity has been estimated at approximately 30 mV/pCreatinine on the [10-1000 mumol L-1] concentration range. The microsensor will be used for blood analysis and more precisely for haemodialysis. (C) 2004 Elsevier B.V. All rights reserved.

3rd generation IR modules - dual-color (DC), dual-band (DB), and large format two-dimensional arrays - require sophisticated production technologies such as molecular beam epitaxy (MBE) as well as new array processing techniques, which can satisfy the rising demand for increasingly complex device structures and low cost detectors. AIM will extend its future portfolio by high performance devices which make use of these techniques. The DC MW / MW detectors are based on antimonide type-II superlattices (produced by MBE at Fraunhofer IAF, Freiburg) in the 384x288 format with a 40 mu m pitch. For AIM, the technology of choice for MW / LW DB FPAs is MCT MBE on CdZnTe substrates, which has been developed in cooperation with IAF, Freiburg. 640x512, 20 mu m pitch Focal Plane arrays (FPAs) have been processed at AIM. The growth of MW MCT MBE layers on alternate substrates is challenging, but essential for competitive fabrication of large two-dimensional arrays such as megapixel (MW 1280x1024, 15 mu m pitch) FPAs. This paper will present the development status and latest results of the above-mentioned 3rd Gen FPAs and Integrated Detector Cooler Assemblies (IDCAs).

NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT 2015年 796卷 85-88页

作者： Bisello, Francesca Menichelli, David Scaringella, Monica Talamonti, Cinzia Zani, Margherita Bucciolini, Marta Bruzzi, Mara Univ Florence Florence Italy Azienda Osped Univ Careggi Florence Italy INFN Florence Div Sesto Fiorentino Italy IBA Dosimetry GmbH D-90592 Schwarzenbruck DE Germany Univ Erlangen Nurnberg D-91054 Erlangen Germany

New tools for dosimetry in external beam radiotherapy have been developed during last years in the framework of the collaboration among the University of Florence, INFN Florence and IBA Dosimetry. The first step (in 2007) was the introduction in dosimetry of detector solutions adopted from high energy physics, namely epitaxial silicon as the base detector material and a guard ring in diode design. This allowed obtaining state of the art radiation hardness, in terms of sensitivity dependence on accumulated dose, with sensor geometry particularly suitable for the production of monolithic arrays with modular design. Following this study, a 2D monolithic array has been developed, based on 6.3 x 6.3 cm(2) modules with 3 mm pixel pitch. This prototype has been widely investigated and turned out to be a promising tool to measure dose distributions of small and IMRT fields. A further linear at prototype has been recently design with improve spatial resolution (1 min pitch) and radiation hardness. This 24 cm long device is constituted by 4 x 64 mm long modules. It features low sensitivity changes with dose (0.2%/kGy) and dose per pulse (+/- 1% in the range 0.1-2.3 mGyfpulse, covering applications with flattened and untlattened photon fields). The detector has been tested with very satisfactory results as a tool for quality assurance of linear accelerators, with special regards to small fields, and proton pencil beams. In this contribution, the characterization of the linear array with untlattened MV X-rays, Co-60 radiation and 226 MeV protons is reported. (C) 2015 Elsevier B.V. All rights reserved.

The integration of multi-functional and reconfigurable aspects into adaptive optics systems is novel for the Micro-electro-mechanical Deformable Mirror (MEM-DM) based applications being presented [1]. It reduces the complexity, cost, size, and maintenance of the system, while increasing real-time flexibility. Multi-functional implies the inherent non-physical reordering of system aspects to produce desired outputs within a self contained autonomous operating system. Traditional solutions to, adaptive optic systems required changing equipment (LCD's for Beam Shaping, Beam Splitters for Beam Splitting, Gimbaled mechanical devices for beam steering, etc.), which is not required with this innovative system design [2,3]. Re-configurable implies the ability to continuously change the systematic operation of an autonomous system through intervention of logic that is designed proactively within the system that is reprogrammable in the field by remote configuration downloads via wireless and/or direct conductive media. The introduction of the 3-D Advanced Optical Phased Array (AOPA) and Phase Retrieval Techniques provides the engine that enables these advancements once applied to the MEM-DM array.

The aim of this paper is to determinate an optimum nonselective etching solution in order to manufacture an as thin as possible, uniform and high quality GaAs membrane. Three different etching systems in various proportions of the components were analysed. A high quality 10 mu m thin GaAs membrane was obtained using the [1(H3PO4)] : [1(CH3OH)] : [3(H2O2)] etching solution. The micromachined GaAs membranes are manufactured to be used as support for microwave circuits as well as in high temperature sensor applications.

Diode-pumped solid-state (DPSS) lasers are increasingly used in industrial high-power applications, including laser ignition. Optimizing such devices requires detailed knowledge of the underlying processes of laser beam creation. To monitor the dynamics of the lasing element's response to mu s pump pulses, we developed a laser interferometric in-situ method capable of measuring the temperature rise in the laser rod, its expansion and the injected heat in real-time. These measurements lead to a better understanding of thermal lens effects and enable the development of improved, energy efficient cooling of the laser rods. (C) 2010 Published by Elsevier Ltd.

Spark is one of the most widely used frameworks for data analytics that offers fast development of applications like machine learning and graph computations in distributed systems. In this paper, we present SPynq: A framework for the efficient utilization of hardware accelerators over the Spark framework on heterogeneous MPSoC FPGAs, such as Zynq. Spark has been mapped to the Pynq platform and the proposed framework allows the seamlessly utilization of the programmable logic for the hardware acceleration of computational intensive Spark kernels. We have also developed the required libraries in Spark that hides the accelerator's details to minimize the design effort to utilize the accelerators. A cluster of 4 nodes (workers) based on the all-programmable MPSoCs has been implemented and the proposed platform is evaluated in a typical machine learning application based on logistic regression. The logistic regression kernel has been developed as an accelerator and incorporated to the Spark. The developed system is compared to a high-performance Xeon cluster that is typically used in cloud computing. The performance evaluation shows that the heterogeneous accelerator-based MpSoC can achieve up to 2.3x system speedup compared with a Xeon system (with 90% accuracy) and 20x better energy-efficiency. For embedded application, the proposed system can achieve up to 40x speedup compared to the software only implementation on low-power embedded processors and 30x lower energy consumption.

High brightness, high average power, diode pumped Nd:YAG solid state lasers (DPSSL) are being developed by TRW as part of the Precision Laser Machining Technology Reinvestment Program. The use of diode pump arrays in place of flashlamps, and zig-zag slab geometry, allow lasers to be scaled to power beyond the current generation of lamp-pumped rod lasers while providing excellent beam quality. The efficiency is 3 - 4 times better using diode arrays in place of flashlamps resulting in less waste heat in the laser medium and reduced optical aberrations. The corresponding beam quality provides more than an order of magnitude increase in the average intensity available at the workpiece, thus enabling new machining capabilities.
