Electric Field Properties of CdTe Nuclear Detectors
2006 IEEE Nuclear Science Symposium Conference Record, 2006Recently, diode-like In/CdTe/Pt detectors have been realized which look very promising thanks to their enhanced spectroscopic performance. Scope of this work is to investigate the electric field distribution inside these detectors and its temporal evolution by means of the Pockets effect.

Properties of Thermistor Infrared Detectors
Journal of the Optical Society of America, 1953Thermistor bolometers are fast, sensitive infrared detectors with good responsivity from 1 to 15 microns. The detectors consist of a thin flake of thermistor material mounted on a thermal sink. The time constant of the detectors is determined by the type of thermal sink on which the flakes are mounted.

Tuning properties of the auditory frequency-shift detectors
The Journal of the Acoustical Society of America, 2009Demany and Ramos [(2005). J. Acoust. Soc. Am. 117, 833–841] found that it is possible to hear an upward or downward pitch change between two successive pure tones differing in frequency even when the first tone is informationally masked by other tones, preventing a conscious perception of its pitch. This provides evidence for the existence of automatic

Simulation of the collection properties of CdTe strip detectors
IEEE Transactions on Nuclear Science, 2001CdTe is an attractive material for X-ray and gamma-ray detectors, but the poor transport properties of holes affect the performance by introducing a low energy tailing in the observed spectra. A possible solution to this problem is to optimize the electrode geometry, for example, by reducing the dimension of the anode with respect to the cathode.

Properties of a Light-Modified-Breakdown Detector in GaAs
Applied Optics, 1973The properties of a bulk-effect millimeter-wave detector made from high-purity epitaxial GaAs are discussed. The devices are operated at 4.2 K in a new light-modified-breakdown (LMB) mode with dc bias above avalanche breakdown. When operated in the LMB mode as a direct video detector, circuit-limited response time (10-90% pulse) less than 20 nsec is ...

Some Properties of Presence Detectors
Transportation Science, 1970Presence detectors on highways record whether or not there are any cars on some nonzero length section of highway. The absence of cars is used as a criterion for switching a vehicle-actuated signal. The problem considered here is the following. Cars pass the detector according to a Poisson process, at velocities that are independent, identically ...

A differentiation / enhancement edge detector and its properties
IEEE Transactions on Systems, Man, and Cybernetics, 1985A differentiation/enhancement edge detector for noisy situations is proposed. The definition of the gradient has been initiated from the algorithm for finding a border in a binary picture. The advantages of this operator have been compared with those of other widely used operators. A measurement of error in extracting edges by thresholding the gradient

Fundamental Properties of Superheated Drop (Bubble) Detectors
Radiation Protection Dosimetry, 1999Superheated drop detectors and bubble damage detectors find increasing applications in ionising radiation dosimetry and spectrometry. These emulsions of overexpanded halocarbon droplets can be manufactured to respond selectively to densely ionising particles, such as neutron recoils, or to all directly and indirectly ionising radiations.

Properties of Frequency Difference Detectors
2009Among other applications, frequency-tracking loops are employed in digital-data receivers, either as a frequency-acquisition aid for phase-locked coherent reception, or as the sole carrier-frequency control for noncoherent reception. This article provides details of design and performance of the frequency-difference detector that lies at the heart of ...
