ACTIVE BLADE TRACKER AND RELATED SYSTEMS AND METHODS

摘要

Devices, methods and systems are provided for monitoring movement of an object (120), such as rotation of a blade (120) or other airfoil. One exemplary tracking device (102) includes a first emitter (140) to emit first radiation along a first line of sight (105), a first detector (142) proximate the first emitter (140) to detect the first radiation, a second emitter (160) to emit second radiation along a second line of sight (107), and a second detector (162) proximate the second emitter (160) to detect the second radiation.
