Zero Magnetic Field Type Magnetic Field Sensor
IEEJ Transactions on Electronics, Information and Systems, 1990 AbstractThis paper presents a new magnetic field sensor named the zero magnetic field type, on the basis of its principle of operation, which is as follows: when the magnetic field level in the core used as a sensor is shifted by an unknown field to be detected, a controlled field is so superimposed in the opposite direction to the unknown field that ...

Radio Frequency Precession Modulation-Based Magnetic Field Sensors
IEEE Access, 2022 High sensitivity is often the foremost characteristic for magnetic field sensors; however, the most sensitive systems tend to be attributed with being any combination of large in size, high in power consumption, complex in design, or exorbitant in cost ...

Effect of magnetic field on magnetic anisotropy sensor.
Journal of the Magnetics Society of Japan, 1991 Nondestructive methods for measurement of mechanical stress are important to studies of magnetic materials. Magnetic anisotropy sensors (MAS), which have been employed in stress and torque sensors, can also be utilized in the noncontact detection of magnetic anisotropy in materials to estimate stress or defects in them.

A Micromachined Resonant Magnetic Field Sensor
2000 Solid-State, Actuators, and Microsystems Workshop Technical Digest, 2000 A micromachined magnetic field sensor has been designed, fabricated and tested. Its principle of operation is based on the change of resonant frequency of a magnetically sensitive micromechanical resonator as a function of applied external magnetic field. Magnetic sensitivity is achieved by incorporating magnetically soft (permeable) or hard (permanent

Towards Uniform Point Density: Evaluation of an Adaptive Terrestrial Laser Scanner
Remote Sensing, 2019 One of the intrinsic properties of conventional terrestrial laser scanning technology is the unevenness of its point density over the scene where objects rendered closer to the scanner are more densely covered than the ones far away.
