Characterizing gravitational wave detector networks: from A ♯ to cosmic explorer

Classical and quantum gravity
Gravitational-wave observations by the laser interferometer gravitational-wave observatory (LIGO) and Virgo have provided us a new tool to explore the Universe on all scales from nuclear physics to the cosmos and have the massive potential to further ...

General Characteristics of Detectors

1987
As an introduction to the following chapters on detectors, we will define and describe here some general characteristics common to detectors as a class of devices. For the reader without detector experience, these characteristics will probably take on more significance when examples of specific detectors are treated.

Third-generation infrared photon detectors

Optical Engineering, 2003
Hitherto, two families of multielement detectors have been used for IR applications: scanning systems (first generation) and staring systems (second generation). Third-generation systems are being developed nowadays. In the common understanding, third-generation IR systems provide enhanced capabilities-like larger numbers of pixels, higher frame rates,

Detectors for the next-generation PET scanners

Il Nuovo Cimento C, 2009
Next-generation PET scanners are expected to fulfill very high requirements in terms of spatial, energy and timing resolution. Modern scanner performances are inherently limited by the use of standard photomultiplier tubes. The use of Silicon Photomultiplier (SiPM) matrices is proposed for the construction of a small animal PET system with depth of ...

Second Generation Gravitational Wave Detectors

Frontiers in Optics 2007/Laser Science XXIII/Organic Materials and Devices for Displays and Energy Conversion, 2007
I will describe the latest in laser interferometers for gravitational wave detection. These instruments are being designed to have CW circulating power levels of ~1 megawatt and sense mirror motions at the 10-20meters/rHz level.

Generic and programmable Timing Generator for CCD detectors

2014 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2014
Charge Coupled Devices (CCD) detectors are frequently used in imaging payloads developed for different satellite applications like space based astronomy and earth observations. CCD’s are been used for onboard/satellite applications as it provides lower noise and higher dynamic range than CMOS detectors.

SECOND GENERATION GRAVITATIONAL WAVE DETECTORS

The Twelfth Marcel Grossmann Meeting, 2012
Second generation gravitational wave detectors are in the process of being researched, designed, and constructed. They include Advanced LIGO in the United States, Advanced Virgo in Italy, the Large Cryogenic Gravitational-wave Telescope in Japan, GEO High Frequency in Germany, and the Australian International Gravitational Observatory in Australia.

Generating feature detectors with discovery algorithms

Proceedings of the IEEE 1993 National Aerospace and Electronics Conference-NAECON 1993, 2002
Traditional techniques for extracting features from images are highly structured processes which require human experts to convert their intuition and experience into algorithms that solve problems such as image classification, target recognition, or assembly line inspection. Intelligent systems such as rule-based expert systems have been used to assist

Delay-locked loop with generalized detector characteristic

Proceedings of ISSSTA'95 International Symposium on Spread Spectrum Techniques and Applications, 2002
The delay-locked loop (DLL) is a synchronization device that is often used for PN-code tracking in spread spectrum systems. The delay detector characteristic of the DLL has a major impact on its performance. Some extensions to provide a modified detector characteristic have been proposed in the past.
