Broadband Mode in Proton-Precession Magnetometers with Signal Processing Regression Methods

چکیده
The choice of the signal processing method may improve characteristics of the measuring device. We consider a measurement error of the signal processing regression methods of a quasiharmonic signal generated in a frequency selective device. The results applied to analyze the difference between the simple period meter processing and regression algorithms using measurement cycle signal data in protonprecession magnetometers. Dependencies of measurement error on sensor quality factor and frequency of nuclear precession are obtained. It is shown that regression methods considerably widen the registration bandwidth and relax the requirements to the magnetometer hardware, and thus affects the optimization criteria of the registration system.

The Feasibility of the Airborne Fluxgate Magnetometer as an Exploration Tool – Results from Three Dimensional Numerical Modelling
INTRODUCTION The earliest geophysical exploration strategies relied on measurements of variations in the Earth's magnetic field. Even today, magnetic methods are the most commonly used geophysical exploration techniques because magnetic observations can be made relatively easily and cheaply. Although compasses are the most common type of mechanical device used to measure the horizontal attitude...
متن کاملAll-optical magnetometry for NMR detection in a micro-Tesla field and unshielded environment.
An all-optical atomic magnetometer is used to detect a proton free-precession signal from a water sample polarized in a 0.7 T field and remotely analyzed in a 4 microT field. Nuclear spins are manipulated either by pi/2 pulses or by non-adiabatic rotation. The magnetometer operates at room temperature, in an unshielded environment and has a dual-channel sensor for differential measurements.

Here we report progress toward the measurement of a permanent electric dipole moment (EDM) in hyperpolarized liquid 129Xe which violates invariance under both parity and time reversal. The standard model (SM) predicts atomic EDMs well beyond current experimental limits while many natural extensions to the SM predict EDMs within the expected sensitivity of current experiments. Hence the search f...

In this research, design and fabrication of an integrated heterodyne electrooptic modulator in lithium niobate have been presented. In this modulator, the waveguide is made by using proton exchange process; to exert two high frequency signals, deposited electrodes with Mach-Zender arms between them are used. In this method, every electrical signal is applied on one of the Mach-Zender arms, so t...

Multiple broadband services are carried independently in a highly multimode polymer optical fibre network by selectively launching and detecting several mode groups, while counteracting mode-mixing by adaptive electrical signal processing. With cheap integrated signal processors, mode group diversity multiplexing can offer the same functionality as wavelength multiplexing at lower costs. © 2002...
