Abstract

We have developed a fiber optic gyroscope with accuracy better than 0.01° /s, size about 30 cm3. To reduce the size and the cost, the design utilizes the cheaper and smaller optical components, such as 850 nm light source without temperature control, a small fiber coil with only about 55 m fiber length and a PIN in place of the traditional PIN-FET. In electronic circuit, the minimum configuration with integration and multiplexing of electronic components is used. To guarantee the performance, the output power stability and degree of polarization of light source, the strong birefringence in small coil and I/V conversion in preamplifier circuit has been taken into consideration in the design. Having a small size, low cost and sufficient performance, this kind of fiber optic gyro is suitable for applications in a wide variety of weapon systems.
