Measurement of Distorted Power-Frequency Electric Field With Integrated Optical Sensor

IEEE Transactions on Instrumentation and Measurement, 2019
The measurement of the distorted power-frequency electric field needs to meet some special requirements such as appropriate insulation, quick response, passive measurement, and small size. In this paper, based on the Pockels effect, an integrated optical

Optical measurement of electric fields

SPIE Proceedings, 2003
Local electric field strengths in low density plasmas can be measured directly by Doppler-free two-photon spectroscopy of atomic hydrogen mostly present in such discharges. This method is based on the Stark-splitting of the atomic resonance lines and causes no significant perturbation to the discharge.

Electrical measurement of free space electric field sensors

2016 IEEE Metrology for Aerospace (MetroAeroSpace), 2016
Free space electric field sensor is the important load of satellite to obtain the information of electric field. Analysis of electric field offers a lot of information to the study area of earthquake monitoring, thunderstorm monitoring and radio wave propagation, improving the ability of major natural disasters monitoring.

Measurement of electric field distributions

IRE Transactions on Antennas and Propagation, 1955
The usual method of measuring electric field distributions comprises a receiving antenna at the point of observation, connected by means of a transmission line to receiving apparatus at some distant point. The principal advantage of the method described here is that it eliminates the transmission line and thus makes possible many measurements which ...

Electric field measurement by a LiNbO 3 probe

SPIE Proceedings, 2007
Optical devices have the potential for large scale integration and can be successfully used in mission critical environments; in particular optical probes interacting with electric fields can be used in several electromagnetic compatibility (EMC) and industrial, scientifical and medical (ISM) applications. We describe an electro-optical device based on

Nonperturbing electric field sensor for near field measurement

1998 Conference on Precision Electromagnetic Measurements Digest (Cat. No.98CH36254), 2002
We present a novel electric field measurement system utilising optical technology, which has been developed, tested and calibrated for near field measurement in the frequency region up to 1.8 GHz. The measuring probe is passive, all-dielectric and EMI immune.

Electric field measurement at sea

Oceans '97. MTS/IEEE Conference Proceedings, 2002
Most of the electrometers are based on the measurement of the difference of potential between two electrodes; a major drawback of this method is its low performance since little of the signal energy is used. Indeed, a very small current goes through the equipment, limited by the high impedance of the voltmeter.

Electric field measurements and computational modeling at ultrahigh-field MRI

Magnetic Resonance Imaging, 2007
While magnetic resonance images essentially contain a map of the both circularly polarized components of the RF transverse magnetic fields (B(1) field), the thermal heat and electromagnetic power deposition is generated by the associated electric fields.
