In this work, we propose a point target detection system (PTDS) based on the fpga technology. Instead of adopting the traditional filter-based methods, in the PTDS, we design a pipelined morphological clutter elimination (PMCE) hardware design with the ability of pipeline and parallel computing. Using the PMCE hardware design, the infrared images can be processed in real-time, which thus enhances system performance significantly. To provide seamless data transfers between the PMCE hardware design and the microprocessor, a hardware/software interface component is also designed in the PTDS. Experiments with an application of point target detection for processing real-time 320 x 240 pixel infrared images demonstrate that the PTDS can speed up 18 times the execution time required by using the software method.

A pulsed RADAR approach is investigated to probe acoustic delay lines used as passive sensors. In order to comply with the requirements of compact, low power receiver electronics, a stroboscopic equivalent time sampling approach is demonstrated. A strategy for generating high resolution time delays while allowing for long interrogation durations (up to 5 mu s) is implemented by combining an fpga-based delay generator with commercially available programmable digital delay lines. The measurement sequence of generating interleaved combs is due to the long delay line reconfiguration duration (SPI communication) with respect to the coarse comb (fpga based counter). The response of the sensor is recorded and processed to acquire the coarse acoustic velocity information through magnitude measurement, and an accurate physical quantity estimate is computed thanks to the phase information. We demonstrate an improved software measurement strategy which prevents the slow process associated with a stroboscopic approach and allows to reach refresh rates of up to 20 kHz when probing an acoustic tag for a physical property measurement, while keeping the hardware to a bare minimum.

Based on Wire-free Die on Die disruptive technology (WDoD™), high density memory can be manufactured in a small form factor package size. Stacking known good rebuilt wafers allows high yields while integrating high performance devices. Dual die (DD) and Quad die (QD) DDR3 memories exhibit outstanding performance and show the path to highly densified System in Package (SiP) for Medical, Defense and Industrial markets.

In this contribution, Coincidence Resolving Time (CRT) results with the developed multichannel fpga-TDC are showed as a function of different configurations for both, the sensor bias voltage and the digitizer threshold. The dependence of the CRT with the sensor matrix temperature, the amount of SiPM active area and the crystal type are also analyzed. Preliminary measurements carried out with a crystal array of 2 mm pixel size and 10 mm height have shown time resolutions for the entire 144 SiPM two-detectors ensemble as good as 800 ps.
