A solid-state imager fabricated in CMOS technology is presented for depth information capture of arbitrary 3D objects with millimeter resolution. The system is based on an array of 32x32 pixels that independently measure the time-of-flight of a ray of ligh ...
Several physical quantities of interest are of quantum nature, often measurable as distinct particles. Light is one such example, photons being its particles. In conventional detectors, light is converted onto electrical charges and hence onto a current or ...
This paper presents a new approach for assessing the reliability of nanometer-scale devices prior to fabrication and a practical reliability architecture realization. A four-layer architecture exhibiting a large immunity to permanent as well as random fail ...
As dictated by ongoing technology scaling and the advent of multi-core systems, each new generation of microprocessors and digital signal processors provides higher computing power and data throughput. However, the available bandwidth of the input/output ( ...
Recently, artificial intelligence (AI) systems gain an increasing popularity and their development is fast. One of the most important fields of the AI system development are artificial neural networks (ANN’s) which, due to continuous progress in microelect ...
Autofluorescence is emerging as a useful tool for the detection of early cancers in the bronchi. It has already produced interesting results, which have been implemented in commercial imaging devices. Their design relies on the spectroscopy of the tissues ...
Formation of vanadia species during the calcination of ball milled mixt. of V2O5 with TiO2 was studied by Raman spectroscopy in situ and at ambient conditions. Calcination in air leads to fast (1-3 h) spreading of vanadia over TiO2 followed by a slower pro ...
Highly structured fluorescence is reported for C60 mols. isolated in Ne and Ar matrixes. Their excitation spectra are similar to the gas-phase 2-photon ionization spectrum of C60. Most of the bands seen in emission can be attributed to Herzberg-Teller or J ...
The resonance Raman overtone progressions of I2 in liq. Xe and in CCl4 following excitation in the bound and continuum parts of the B state are discussed and compared with theor. simulations. The intensity distribution of the Raman overtones yields informa ...
The effect of pressure (up to 22 GPa) and temperature (to 1300 K) on the Raman spectra has been measured for pyrope, grossular and andradite garnets. No phase changes were observed and all Raman modes increase or decrease linearly with pressure and tempera ...
