ROTOR MEASUREMENT SYSTEM USING REFLECTED LOAD TRANSMISSION

摘要

An apparatus is provided for obtaining data from sensor measurements made on a body moving rotationally with respect to a stationary observer. Radio frequency energy is reactively coupled between an energy source fixed with respect to the observer and load varying means located on the moving body. The load variance is dependent upon measurement data provided by sensors located on the moving body. The variation in load is reflected back through the reactive coupler to a detector which is fixed with respect to the observer. The detector operates to provide signals indicative of the measurement data provided by the sensor.
