Displacement Sensing of an Active String Actuator Using a Step-Index Multimode Optical Fiber Sensor [PDF]
Sensors, 2022 A thin McKibben artificial muscle is a pneumatic actuator with an outer diameter of only 1.8 mm. We fabricated a string-shaped actuator called an “active string actuator,” which achieves a high contractile displacement by accumulating thin McKibben ...

Spatiotemporal control of ultrafast pulses in multimode optical fibers [PDF]
Nature CommunicationsMultimode optical fibers represent the ideal platform for transferring multidimensional light states. However, dispersion degrades the correlations between the light’s degrees of freedom, thus limiting the effective transport of ultrashort pulses between

Multimode fiber optic sensors [PDF]
The Journal of the Acoustical Society of America, 1990 A theoretical approach useful in the design of multimode optical fiber sensors is described. An intensity distribution function is derived when assuming that a multimode optical fiber is illuminated by a light source that can be approximated by infinite uniangular beams carrying equal power.

Deep learning of ultrafast pulses with a multimode fiber
APL Photonics, 2020 Characterizing ultrashort optical pulses has always been a critical but difficult task, which has a broad range of applications. We propose and demonstrate a self-referenced method of characterizing ultrafast pulses with a multimode fiber. The linear and
