We have developed a magnetic position sensor to enhance the stability of scanning fiber endoscopes, addressing a key challenge for their clinical use. The sensor employs micro-magnet at the fiber tip, generating a dynamic magnetic field as the scanner operates. A 3D Hall sensor within the probe housing measures this magnetic field and maps it to the beam position using calibration curves derived from a one-time calibration with a position-sensitive detector. This innovation promises to overcome the inherent short- and long-term position instability that has, until now, limited the broader clinical adoption of these vital instruments.
