System on Chip based compact NQR Spectrometer

Résumé

Nuclear Quadrupole Resonance (NQR) is a radio frequency spectroscopy technique providing high resolution molecular structure analysis of solid materials containing quadrupole atomic nuclei. Despite its relatively low sensitivity, the fact that no heavy equipment is needed to generate the spin polarization makes it potentially very useful for low cost and portable applications. The challenges of NQR instrumentation are therefore to increase its portability and sensitivity, and limit interference from various noises sources (e.g. radio frequency inference), in order to perform field applications outside the laboratory. To address this challenge, we present a System on Chip solution (SoC) integrating the major blocks of the spectrometer including: a high time resolution pulser, a fully controllable pulse transmitter, an acquisition module, and a hardware debugger. The design of the proposed solu- tion is verified using behavioral simulation and validated on board. While most recent compact spectrometers still have crucial RF parts in the analog domain, our hardware and software modules are directly implemented on the Xilinx Zynq FPGA.
