This paper presents a method for characterizing electric field profiles of radio frequency (rf) quadrupole ion trap structures using sensors based on slab coupled optical-fiber sensor (SCOS) technology. The all-dielectric and virtually optical fiber-

In this paper we measure for the first time the full-spectral response of a fiber Bragg grating (FBG) sensor subjected to vibration. We consider two cases: with and without an initial spectral distortion due to non-uniform strain along the length of

We report the development of a temporally stable in-fiber electric field sensor using electro-optic (EO) polymer. The design consists of partially replacing the core of a D-fiber with AJL8/APC EO polymer resulting in a device insertion loss less than

This paper shows a method allowing electric field sensing in high vibration environments. The vibration sensitivity is reduced using a push-pull configuration and external phase modulation. This paper provides both theoretical description and experim

One of the most common methods used to measure high voltage is using a voltage divider. While this method is fairly reliable for most low frequency high voltage measurements, the voltage divider encounters difficulty when measuring higher frequency v

We describe the application of SCOS technology in non-intrusive, directional and spatially localized measurements of high electric fields. When measuring electric fields above a certain threshold, SCOS measurement sensitivity starts varying to a grea

The push-pull slab-coupled optical sensor measures a localized single electric field component with the advantage of reducing adverse strain effects for sensing in harsh vibrating environments. Its miniature size makes it ideal for compact environmen
