title = "Feedback control of optical propulsion velocity of microparticles in hollow-core fibers",
abstract = "Hollow-core optical fibers provide an ideal solution for long-distance object guidance and delivery. We report a real-time monitoring and feedback control on the propulsion velocity of flying microparticles in hollow-core fibers. Doppler velocimetry is employed to acquire the instantaneous velocity of the particle, and PID algorithm is exploited to adjust the laser power through an acousto-optic modulator based on the measured particle velocity. The technique can guide particles over the fiber with controlled speed, benefiting the application of targeted object deliveries.",
