The Photon Counting in Sinogram of CT is according to the Poisson distribution of X-ray photons. And every Sinogram contains the components of Pixel imaging, and every components receive the photons. So the numbers of photons in the components are the random numbers according to the Poisson distribution. Adding these random numbers, that is Sinogram become to the random numbers according to...
Ge detectors are widely used as X-ray/γ-ray detectors, but they cannot operate at room temperature due to narrow bandgap, must be cooled with liquid nitrogen. As a better material, CdTe, which can operate at room temperature and has a large attenuation coefficient, is becoming more widely used. However, compared to Ge, the manufacturing process has not been optimized and the manufacturing cost...
BT.2020's color gamut includes 99.9% of that of Pointer colors, which is colorimetric data representing the gamut of real surface colors. For this reason, BT.2020 compliant Ultra High Definition (UHD) displays are required to have a wider color gamut than High Definition (HD) displays. Light-emitting devices and color filters are being developed for UHD displays. Due to issues with...
This paper presents theoretical study of phenomenon of stimulated Brillouin scattering of q-Gaussian laser beams in nonlinearly-interacting with underdense plasmas. During propagation of intense laser beam with ω0, it gets coupled to pre-existing ion acoustic wave (IAW) at frequency ωia due to relativistic mass nonlinearity of plasma electrons. The nonlinear interaction of pump beam with IAW...
The phenomenon of stimulated Raman scattering (S.R.S) of intense self focused Cosh-Gaussian (ChG) laser beams in underdense plasma targets modeled by a ramp shaped different density profiles, has been investigated. An intense laser beam with frequency ω0 propagating through plasma gets coupled with a pre-existing electron plasma wave (EPW) at frequency ωep and produces a back scattered wave...
LIBS (Laser-Induced Breakdown Spectroscopy) allows to measure the concentration of major and trace elements in solid, liquid, or air samples. LIBS technology has the advantage of adapting the research to any situation, from online measurements in an industrial environment to analyses in the laboratory.
LIBS technology is designed to meet detection and analysis needs in a wide variety of...
