As mentioned earlier, Allan variance was first used to measure the frequency stability of precision oscillators and has spread out to other applications. For example, the Allan variance is widely used to examine the random errors of MEMS gyroscopes. In this case, the Allan variance gives the root ... Allan variance is used as a measure of frequency stability in a variety of precision oscillators, such as crystal oscillators, atomic clocks and frequency-stabilized lasers over a period of a second or more. Short-term stability (under a second) is typically expressed as phase noise. The Allan variance is also used to characterize the bias stability of gyroscopes, including fiber optic gyroscopes, hemispherical resonator gyroscopes and MEMS gyroscopes and accelerometers. taehyung favorite food
