Technical publications linked to our expertises
Thanks to the high innovation rate of our company, Kapteos is frequently publishing technical papers during seminars, exhibitions, conferences, symposiums or after tests that highlight a noticeable measuring performance or a first-ever result.
These publications follow the peer-review process where recognized international experts, criticize, comment and validate the submitted papers which must contain a significant novelty.
This page shows only abstracts and the beginning of the introduction of the technical publications. For more information on a publication, please contact us.
Pulsed power and intense electric field now apply to a large variety of domains for which the need of in situ nonperturbative measurements remains a challenge.
We have developed ultra compact and fully dielectric pigtailed optical sensors for a simultaneous 2-components electric-field measurement. Their measurement dynamic covers the V/m up to MV/m electric-field strength range.
Magnetic Resonance Imaging (MRI) is based on a spatial characterization of the nuclear magnetization. Recording the variation of the nuclear magnetization is often realized with a MRI external surface coil. However, spatial resolution and image quality achievable with external surface coils are limited.
Radio frequencies constitute a part of the electromagnetic (EM) spectrum extensively exploited for many domestic, industrial, and medical applications. Their massive use has led to new questions about the potential effects on health of this non-ionizing radiation.
In this paper, we present radio-frequency electromagnetic field characterization of an electrooptic (EO) probe. This probe is able to simultaneously measure temperature and one component of the electric field (e-field) in a continuous wave (CW) or in a pulsed regime.
New Method for in Live-line Detection of Small Defects in Composite Insulator Based on Electro-optic E-field Sensor
Preliminary results based on experimental tests in laboratory and numerical investigation concerning the live-line detection of a conductive defect in HV composite insulator are depicted. The proposed method is based on E-field sensor.
Simultaneous High Intensity Ultrashort Pulsed Electric Field and Temperature Measurements Using a Unique Electro-Optic Probe
High intensity nanosecond pulsed electric fields and temperature were simultaneously measured using a unique electrooptic (EO) probe. The measurements were performed in an electroporation cuvette with 4 mm electrode gap and filled with a buffered salt solution.
In this letter, the temperature measurement ability of an electrooptic probe as well as specific absorption rate (SAR) assessments via simultaneous in situ temperature and electric field characterization are reported.
Based on an isotropic electro-optic crystal, a two-port pigtailed electro-optic sensor has been built. The probe allows to measure two orthogonal components of the ambient electric field. The sensor intrinsically presents a temperature-dependent free response.
In this article, we present a new family of chipless tags, which permit encoding of digital data in the terahertz domain. These devices consist of stacked dielectric media whose thicknesses are of the same order as terahertz wavelengths.
