Simple question (I hope) but how accurately can linear and/or angular velocity be measured, with a view to generating a clock signal from the measured rotation? I'm wondering if it would be possible ...

Ask any engineer what the velocity of a point on a rigid body is, and they will correctly say that it's the time rate of change of a linear position vector. Ask any engineer what angular velocity is, ...

The Doppler effect is a universal wave phenomenon that has spurred a myriad of applications. In early manifestations, it was implemented by interference with a reference wave to infer linear ...

Applications that require precise information on the linear or angular movement of an object rely on the accuracy of motion sensors within. Accelerometers and gyroscopes can be used to provide this ...
