Abstract
The present invention relates to an optical probe () suitable for miniature applications. An example application is a fiber-based confocal miniaturized microscope. The optical probe comprises a coil-based actuation system () comprising drive coils () capable of displacing the distal end () of an optical guide () housed () by the optical probe. The probe makes use of a feedback loop which alternate between driving the displacement of the optical guide by driving a current through the drive coils and switching off the current through the drive coils, and while the drive current being switched off, measure the speed of the distal end of the optical guide. The measured speed is compared to the set-point speed, and if a difference is detected, the drive current is adjusted to eliminate, or at least bring down, this difference.
