The Interferometer Fiber Optical Gyroscope has an optical path of L=1.5 km, coil diameter = 20 cm, the optical index of fiber is 1.4606, laser light frequency is 4.5X1014 Hz, the Sagnac phase shift can be calculated using the above equation. In the system, there is a detector to detect the sagnac phase shift. However, due to the operational nature of the detector, the maximum detectable ^% of the detector is , 1) calculate the maximum detectable rotation rate 2max (in the unit of degree/hour). 2) the resolution of the detector is 0.5X10-6 rad, please calculate that is resolution of this gyroscope.
