Abstract
This paper describes the operating principle and construction of a new type of rotary motion sensor. This novel optical device is based on a patented evolution of the high precision optical shaft encoder. It integrates highly accurate measurement of the angular position and 2D center position of a rotating shaft. The current work described is aimed specifically at using this sensor for monitoring the condition of rolling element bearings. The process by which the output from four stationary, non-contact, fiber optic sensing heads can scan a coded disk coupled to a shaft and derive its center position to approximately 30 nanometers at an angular resolution of approximately 0.0005 min is explained. The design and implementation of the computer architecture to which the sensor is interfaced via noise immune fiber optic links and the algorithms which underlie the processing software are also examined.
