摘要： An absolute position fiber optic encoder readhead having multiple readhead portions for sensing the displacement of respective scale grating tracks of a scale is disclosed. The detector channels of the readhead portions are fiber optic detector channels having respective phase grating masks. The fiber optic encoder readhead portions are configured to detect the displacement of a self-image of a respective scale grating track of the scale. In various exemplary embodiments, the fiber optic readhead portions are constructed according to various design relationships that provide a relatively high signal-to-noise ratio. Accordingly, high levels of displacement signal interpolation may be achieved, allowing submicrometer displacement measurements. The fiber optic encoder readhead portions may be assembled in a particularly accurate and economical manner and may be provided in a package with dimensions on the order of 1–2 millimeters, resulting in a very small overall absolute readhead dimension that is dependent on the number of readhead portions that are incorporated. Optical fiber receiver channels carrying binary optical signals derived from a scale code track may be provided in the readhead, to provide an extended absolute measurement range.

摘要： An inductive absolute position transducer system, usable in high accuracy applications such as linear encoders, has two members movable relative to each other and includes three inductive position transducers. Each inductive position transducer includes at least one transmitter winding for generating a magnetic field and two or more receiver windings for receiving the magnetic field. Each inductive position transducer also includes a plurality of flux modulators which modulate the magnetic field generated by the transmitter winding. Each receiver winding has a plurality of symmetric loops arranged along a measurement axis. The receiver windings of two of the inductive position transducers define two wavelengths that are similar to each other, but not equal. Thus, a phase relationship between the inductive position transducers has a wavelength much longer than the wavelength of either of the two inductive position transducers. An electronic circuit coupled to the inductive position transducers determines the absolute position between the two members. In an alternative embodiment, the inductive absolute position transducer includes only one inductive position transducer, having a fine wavelength. The inductive absolute position transducer includes one or more inductive transducers with a relatively coarse wavelength. An electronic circuit coupled to the inductive position transducers determines the absolute position between the two members, first identifying a coarse absolute position measurement along the measuring axis using the relatively coarse wavelength transducer, and refining this position measurement using information from the inductive position transducer having a fine wavelength.

摘要： A flexure in a force transducer, as an inertial guidance accelerometer, for securing a force sensitive element to a mounting base includes one or more flexure sections having one or more recessed surfaces which are substantially coincident with the neutral bending plane of the flexure. Electrically conductive coating on the recessed surfaces provide electrical connections to components located on the force sensitive element. The conductive coatings on or near the neutral bending plane of the flexure sections minimizes bending moments caused by stresses set up between the conductive coatings and the flexure which may in turn lead to bias errors. At the same time, the flexure configuration provides for the desired strength and spring rate for the force sensitive element.

摘要： The necessity for rigorously controlling process variables or making physical measurements is eliminated in a method of manufacturing a flexure for use in connecting a force sensing element to a mounting base in a force transducer where indicator portions are provided in a blank and material is removed uniformly from the blank including indicator portions until the indicator portions disappear. This process can also be used to configure a flexure out of a unitary piece of material such as fused quartz where a blank is masked except for indicator portions on each surface of the blank and at least one other surface portion; material is removed from the non-masked portions of the blank; and after removing the mask, material is removed from the blank until the indicator portions disappear.

摘要： A chromatic point sensor (CPS) calibration object and characterizing data are provided. The calibration object comprises a flat base plane with steps extending from it. Step measurement points provided by the steps and base plane measurement points provided by portions of the base plane are intermingled along a measurement track. The characterizing data characterizes known heights of the measurement points. A calibration method acquires measurement data such that some base plane measurement points should be at nearly the same measurement distance and therefore have the same common mode errors relative to known base plane measurement point heights. If such base plane measurement points exhibit minimal error variations, then measurements for those and proximate measurement points may provide reliable calibration data. In contrast, error variations outside an expected range indicate unreliable measurements that should be screened or replaced by new calibration measurements.

摘要： An electronic hand tool type caliper includes a scale track located along a scale member reference edge that forms a sliding bearing with a mating surface of the caliper slide, thereby maintaining proper alignment of the slide jaw. Placing the scale track along the reference edge is advantageous in that the reference edge surface is inherently precisely machined and particles are excluded by the inherently close fit and the wiping action of the sliding bearing. A readhead sensor is mounted within the slide surface that mates to the reference edge to provide the sliding bearing. Thus, a very small readhead sensor may be reliably positioned at an extremely small gap relative to the scale in a protected operating environment, without detrimentally affecting cost, slider friction, or signal strength. High resolution digital signals may be provided.

摘要： An absolute 2D position-sensing device is usable to measure the relative position of two elements. A 2D absolute scale includes an integrated 2D absolute scale pattern extending over the 2D scale area along each measuring axis of the scale. The integrated 2D absolute scale pattern includes a plurality of periodic portions interleaved with a plurality of non-periodic portions along each axis. Each periodic portion includes a plurality of periodically-placed scale elements. Each non-periodic portion includes a plurality of code elements indicative of an absolute measurement value. The code elements may have a length that is narrower along each measuring axis is than the length of the periodic scale elements along each measuring axis. The offset of the periodically-placed elements relative to a readhead of the device is combined with the absolute measurement value to determine an absolute position.

摘要： An optical displacement sensing device is provided for determining the relative displacement of a diffraction scale grating that may have a grating pitch less than the wavelength of the light of the sensing device. The sensing device includes a split light beam input portion for inputting two split light beams along respective light paths, and light beam directing elements for directing the two split beams along converging light paths toward a first zone on the scale grating to give rise to two diffracted beams along light paths which diverge. The sensing device further includes retroreflector elements for receiving the two diverging diffracted beams and retroreflecting them along light paths which converge toward a second zone on the scale grating to give rise to two later-diffracted light beams that are then directed to a shared zone. The retroreflectors may be positioned to eliminate cross-over beams and the need for polarizers. An optical detector detects at least one illumination characteristic arising from the shared zone, thus sensing displacement of the scale grating along the measuring axis.
