A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common. The word comes from Greek τάχος (táchos "speed") and μέτρον (métron "meas… Webcircular light waves counter-propagating in a coil of sensing fiber. In the second configuration the coil is operated in reflection5-7. Here, the phase shift is introduced between two co-propagating left and right circular waves that are reflected at the coil end and then retrace the optical path with swapped polarizations.
