【摘要】 本文叙述了光纤陀螺的基本原理及影响其零位漂移的各种噪声，介绍了一种能有效抑制偏振态波动噪声的环形谐振腔光纤陀螺。该陀螺的谐振腔环是由带有光诱导双折射光栅的保偏光纤构成，通过计算，其最大零位漂移被限制在１０－７ｒａｄ／ｓ（０．０２°／ｈ），理论上能满足空间惯性导航系统的要求。更多还原

【Abstract】 In this paper, a mechanical control device for yarn binding process is introduced, and the operating principle of the yarn tension auto regulation and the formation of the yarn motion are analyzed. The formulae for calculating angular velocity of a yarn reel pay off and friction string wrapping angle for tension auto regulation are deduced.更多还原
