Devices, methods and systems are provided for monitoring movement of an object, such as rotation of a blade or other airfoil. One exemplary tracking device includes a first emitter to emit first radiation along a first line of sight, a first detector proximate the first emitter to detect the first radiation, a second emitter to emit second radiation along a second line of sight, and a second detector proximate the second emitter to detect the second radiation.
