ABSTRACT:
An optical torque detecting apparatus for a rotating shaft of which torsional torque is to be detected comprising a pair of rotary plates disposed to face each other connected to the shaft with a predetermined interval between the positions where each is connected to the shaft, each plate having a radial optical grid thereon so that a Moire fringe pattern may be created in accordance with a change of relative turning between the plates caused by torsion of the shaft and a device detecting a shift of the Moire fringe pattern between radially inner and outer sections of the optical grids.
