    摘要： An optical scale, a method for manufacturing an optical scale, and an optical encoder less affected by fluctuations in the amount of detected light and with an improved resolution are provided. The optical scale is an optical scale through which or on which light source light from a light source is passed or reflected. The optical scale includes a plurality of wires provided thereon so that the plurality of wires do not intersect each other and each of the tangential directions of the respective wires changes continuously. The optical encoder includes the optical scale, a light source, an optical sensor, and a computing unit. The optical sensor includes a first polarizing layer that splits incident light that is light source light from the light source passed through or reflected on the optical scale and being incident on the first polarizing layer to a first polarization direction, a second polarizing layer that splits the incident light to a second polarization direction, a first photoreceiver that receives first polarized light split by the first polarizing layer, and a second photoreceiver that receives second polarized light split by the second polarizing layer. The computing unit computes a relative movement of the optical scale with respect to the optical sensor from the light intensities of the first polarized light and of the second polarized light.

    摘要： According to one aspect of the invention, a method for calibrating a torque measurement for a rotatable object (114) is disclosed, wherein the method includes coupling the rotatable object (114) to a structure (202), the structure including a member (208,210) extending along a length of a surface of the rotatable object (114), coupling the rotatable object to an adapter (204) and applying a known torque to the rotatable object (114) via the adapter (204). The method also includes measuring a first rotational displacement via a first sensor (214) coupled to the member (208,210) at a first axial location of the rotatable object (114), measuring a second rotational displacement via a second sensor (220) coupled to the member at a second axial location of the rotatable object (114) and determining first and second angular displacements of the rotatable object (114) based on the first and second rotational displacements.

    摘要： A torque transducer comprising a rotating shaft having first and second torque input members (1a, 1b) connected by a torsionally compliant coupling (2) 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 having an EMR source (5, 6) and an array or EMR sensitive detectors (7, 8). Each of the torque input members having a grating zone (101, 102) with alternating regions of high and low transmissibility to the EMR. The grating zone resides in the transmission path (90, 91) 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 members and provide a measure of the magnitude of the torque in the shaft.
