An angular rate sensor (100; 900) of the class wherein two electromagnetic waves travel in opposite directions is disclosed. Each wave is substantially travelling about a closed-loop path wherein the frequency of each of said waves is a function of the rate of rotation of said closed-loop path. In order to provide for correction or reduction of lock-in error, sensing means (110; 910) are arranged to sense at least one of said waves and signal processing means (120, 140, 150, 160; 920, 940, 950) are provided in an open or closed control loop for compensation of lock-in error.
