Introduction

LKF-FS60 is a miniaturized closed-loop fiber optic gyroscope, which breaks through the classical design concept of traditional fiber optic gyroscope. It adopts integrated circuit and optical path design. It has the outstanding characteristics of small volume, light weight, high bandwidth, fast start-up, simple interface and convenient use. LKF-FS60 is an ideal low-precision angular rate sensor in the control field, which is widely used in various inertial measurement and control fields.

By reducing the outer diameter of fiber to 135μm，Thin PM fiber solution decreases extremely the size of fiber coils and delivers outstanding precision performance in fiber coils, which is applied for miniaturization of FOGs. And, the coils are wound precisely through quadrupole symmetry method.

The miniatured fiber optic gyros have excellent advantages of compact and cost-effective, and are easy to integrate and ideal for UAV, photoelectric pod, optical platform, and so on
