A nested coil-and-light-guide layout lets a flux transformer apply the target magnetic field without blocking laser, microwave, or static field access.
A nested coil and light-guide layout lets a flux transformer drive the resonance member while preserving laser, microwave, and static field access.
Optical fiber transmission and photoelectric conversion replace large antennas, preserving insulation and preventing breakdown in high-voltage sensing.
Optical fibers carry excitation light, fluorescence, and microwave-band signals to keep diamond magnetic sensing insulated in high-voltage units.
