Paper Abstract

The minimum bend radius of optical microfiber allows very compact flexural disc accelerometers to be manufactured without significant degradation of the optical signal in terms of attenuation and depolarization. Such compact sensors have potentially very high responsivity in small packages. We demonstrate a responsivity of 4 rad/g between 100-1000 Hz for a disc wound with microfiber of 60-millimeter length and 10-micron diameter microfiber. We report the successful fabrication of a 0.4-meter length and 10-micron diameter microfiber using a new tapering setup and an automated technique is proposed for efficiently winding long lengths of microfiber onto the flexural disc.
