Simultaneous recordings of human microsaccades and drifts with a contemporary video eye tracker and the search coil technique. [PDF]

PLoS ONE, 2015
Human eyes move continuously, even during visual fixation. These "fixational eye movements" (FEMs) include microsaccades, intersaccadic drift and oculomotor tremor.

The Search Coil Magnetometer for THEMIS [PDF]

Space Science Reviews, 2008
THEMIS instruments incorporate a tri-axial Search Coil Magnetometer (SCM) designed to measure the magnetic components of waves associated with substorm breakup and expansion. The three search coil antennas cover the same frequency bandwidth, from 0.1 Hz to 4 kHz, in the ULF/ELF frequency range.

Design of a Compact Space Search Coil Magnetometer [PDF]

Sensors
Search coil magnetometers (SCMs) are widely used in space science missions to measure time-varying magnetic fields. However, conventional SCM designs often increase sensor mass and electronic power consumption in order to meet mission-specific ...

A Novel Design Nomogram for Optimization of Micro Search Coil Magnetometer for Energy Monitoring in Smart Buildings [PDF]

Micromachines, 2022
In this paper, a new analytical method to achieve the maximum signal-to-noise ratio (SNR) of a micro search coil magnetometer (µSCM) is presented. A planar spiral inductor was utilized to miniaturize conventional bulky search coil magnetometers.

The Search-Coil Magnetometer for MMS [PDF]

Space Science Reviews, 2014
Abstract The tri-axial search-coil magnetometer (SCM) belongs to the FIELDS instrumentation suite on the Magnetospheric Multiscale (MMS) mission (Torbert et al. in Space Sci. Rev. (2014), this issue). It provides the three magnetic components of the waves from 1 Hz to 6 kHz in particular in the key regions of the Earth’s magnetosphere namely ...

Optimized merging of search coil and fluxgate data for MMS [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2016
The Magnetospheric Multiscale mission (MMS) targets the characterization of fine-scale current structures in the Earth's tail and magnetopause. The high speed of these structures, when traversing one of the MMS spacecraft, creates magnetic field ...

The Magnetic Search Coil (MSC) on the TRACERS Mission. [PDF]

Space Sci Rev
Abstract The Magnetic Search Coil (MSC) instruments on the TRACERS mission provide the three magnetic components of the waves from ∼1 Hz to 1 kHz from two closely spaced spacecraft in low Earth orbit that pass through the magnetospheric cusp. These measurements of Alfvén and other waves help meet the TRACERS Science Objective 3: “Determine to

Spaced‐based search coil magnetometers

Journal of Geophysical Research: Space Physics, 2016
AbstractSearch coil magnetometers are one of the primary tools used to study the magnetic component of low‐frequency electromagnetic waves in space. Their relatively small size, mass, and power consumption, coupled with a good frequency range and sensitivity, make them ideal for spaceflight applications.
