High density compound materials (CdTe, GaAs, HgI 2) are currently evaluated as direct photon conversion sensors for applications in X-ray imaging. A new front-end stage has been designed with the aim to be implemented as readout chain in a luggage inspection system based on a linear array of CdTe sensors. Both types of electron or hole collecting CdTe… (More)
A practical fully-digital network for pattern recognition is presented here. It consists basically of a Hamming-like Network architecture permitting modularity and is suitable for both semi-custom VLSI and FPGA implementations.
