光纤陀螺是用光学方法测量角度的一种新型敏感元件。由于它没有运动部件,因而具有制造成本低和可靠性高的优势。又由于它结构简单,只有一个激光二极管、一个光电检测器和一只利用廉价光纤制造的线圈,因而使得许多人相信,采用光纤陀螺能避免将投资用于高技术开发之中,而在惯性导航领域,这是竞争能否取得成功的先决条件之一。 Fiber optic gyroscope is a new type of sensitive element that uses optical methods to measure the angle. Because it has no moving parts, it has the advantage of low manufacturing cost and high reliability. And because of its simple structure, with only one laser diode, a photodetector, and a coil made of cheap fiber, many believe that the use of fiber optic gyroscopes to avoid investing in high-tech development can lead to inertial navigation One of the prerequisites for the success of the competition.
