Abstract
A torque transducer comprises a rotating shaft having first and second torque input members connected by a torsionally compliant coupling thereby enabling angular deflection of the torque input members relative to each other as a function of the magnitude of the torque in the shaft. The transducer has an EMR source and an array of EMR sensitive detectors. Each of the torque input members has a grating zone with alternating regions of high and low transmissibility to the EMR. The grating zone resides in the transmission path communicating EMR from the source to the array. A pattern is produced by incident EMR on the array resulting from the alternating regions of high and low transmissibility of the grating zones residing in the transmission path to the array. The pattern on the array is processed to derive the relative angular deflection of the torque input members and provides a measure of the magnitude of the torque in the shaft.
