High Resolution X-Ray Spectroscopy with Compound Semiconductor Detectors and Digital Pulse Processing Systems
The advent of semiconductor detectors has revolutionized the broad field of X-ray spectroscopy. Semiconductor detectors, originally developed for particle physics, are now widely used for X-ray spectroscopy in a large variety of fields, as X-ray fluorescence analysis, X-ray astronomy and diagnostic medicine. The success of semiconductor detectors is due to several unique properties that are not...
متن کاملA Bayesian method for pulse shape and energy estimation for gamma spectrometry measurements using semiconductor detectors
Abstract. The gamma spectroscopy principle is to evaluate a gamma ray energy by measuring the quantity of free charges generated by the gamma-ray absorption. Semiconductors like CdTe and CdZnTe are promising materials for this application. However, they encounter a major drawback: due to imperfections in their charge transport properties, the transient signal induced by a gamma ray has a varyin...
متن کاملCharge transport in arrays of semiconductor gamma-ray detectors.
We analyze the effects of electrode size on performance of arrays of semiconductor gamma-ray detectors, especially when there is significant charge trapping. With large electrodes, motions of holes and electrons are of equal importance, but when the positive electrode is segmented into an array of small elements the contributions of holes to the output, and hence the effects of hole trapping, a...
متن کاملDigital Image Watermarking Technique Using Discrete Wavelet Transform And Discrete Cosine Transform
Digital watermarking has been proposed as a viable solution to the need of copyright protection and authentication of multimedia data in a networked environment, since it makes possible to identify the author, owner, distributor or authorized consumer of a document. In this paper a new watermarking technique to add a code to digital images is presented: the method operates in the frequency doma...
متن کاملHiding digital watermarks using multiresolution wavelet transform
In this paper, an image accreditation technique by embedding digital watermarks in images is proposed. The proposed method for the digital watermarking is based on the wavelet transform. This is unlike most previous work, which used a random number of a sequence of bits as a watermark and where the watermark can only be detected by comparing an experimental threshold value to determine whether ...
