This review presents the main characteristics and mechanisms of operation superconductor–insulator–normal metal–insulator–superconductor (SINIS) microwave detectors. An analysis detectors’ performance against a quantum detector photon counter is given. Methods for cooling superconductor using normal metal traps role electron in optimizing current response to terahertz radiation are discussed. F...

The ability to detect individual light quanta – single photons is prized across many fields of physics from astronomy quantum optics. Superconducting photon detectors offer exceptional performance in terms sensitivity, spectral range and timing resolution. In this review, we introduce the underlying absorption superconducting devices. We then present detailed case studies contemporary detector ...

one of the most fundamental features of digital image and the basic steps in image processing, analysis, pattern recognition and computer vision is the edge of an image where the preciseness and reliability of its results will affect directly on the comprehension machine system made objective world. several edge detectors have been developed in the past decades, although no single edge detector...

given the sensitivity of current ground-based gravitational wave (gw) detectors, any continuous-wave signal we can realistically expect will be at a level or below the background noise. hence, any data analysis of detector data will need to rely on statistical techniques to separate the signal from the noise. while with the current sensitivity of our detectors we do not expect to detect any tru...

background: in high-intensity, mixed and pulsed neutron fields the use of spectrometers or area monitors with active detectors is useless in these conditions neutron measuring devices must have a passive detector. here a passive neutron area monitor with cr39 track detector was designed and the response was calculated. materials and methods: the response of a passive neutron area monitor with c...
