Devices, systems, and methods that utilize a ferrofluid-impregnated medium to impart motion to an optical fiber positioned within an imaging probe are provided. In some embodiments, an ophthalmic imaging probe can include a housing having a proximal portion and a distal portion an optical fiber positioned within the housing, the optical fiber configured to receive an imaging light from an imaging light source and guide the imaging light to an optical element positioned within the distal portion of the housing and an actuator system configured to impart motion to the optical fiber, the actuator system including a ferrofluid-impregnated medium (FIM) and an electrically energizable coil positioned within the housing.
