Abstract

An all-fiber gyroscope that uses a 1.06-microm multicore Nd-doped fiber source pumped by a laser-diode array is demonstrated. Intensity noise subtraction is used to reduce the excess noise that arises from a source bandwidth limitation. The random walk coefficient is improved by a factor of 3, to 2.5 x 10(-4) deg radicalh (1-km fiber, 16-cm radius).

摘要

展示了一种全光纤陀螺仪，它使用由激光二极管阵列泵浦的1.06微米多芯掺钕光纤源。采用强度噪声减法来减少由源带宽限制引起的过量噪声。随机游走系数提高了3倍，达到2.5×10⁻⁴度/√小时（1公里光纤，16厘米半径）。
