Abstract: A method establishing a reference point for a machine tool with X-, Y-, and Z-stages. A YZ-plane is established by reflecting a light beam off an X-stage reflector such that the light beam is sensed at an interference detector. The X-stage is moved while repositioning the head and reflector and maintaining sensing. An optical alignment module (OAM) is mounted optically perpendicular to the beam, with a bending mirror centered at the Z-axis. The Z-axis is established by setting the bending mirror to deflect the beam to the Z-axis, reflecting it off of a Z-stage reflector so it is sensed, and moving the Z-stage while repositioning the OAM relative to the X- and Y-axes to maintain sensing. An XY-plane is established by bending mirror deflecting the beam to the Y-axis, reflecting it off of a Y-stage reflector so it is sensed, and moving the Y-stage while repositioning the Y-reflector relative to the X- and Z-axes to maintain sensing.

There is a plurality of reflective patterns at the bottom surface of the guiding element. Each reflective pattern is composed of at least one concavity and at least one convexity.

As the light source emits light to the guiding element, the reflective area is increased by the concavity of the reflective pattern for increasing the reflecting effect and for distributing the brightness more uniformly, and thereby higher brightness and uniformity can be achieved.

Abstract: A contactless rotary shaft rotation sensor includes a two-pole annular magnet attached directly to the shaft, pairs of diametrically opposed magnetic field sensors, and electronic processing circuits to produce linear output signals proportional to shaft speed and position. The annular magnet has two diametrically opposed poles on its outside circumference and is magnetized with a magnetic iron pole piece temporarily placed through its inner diameter to magnetically shape the poles and provide an extremely linear flux variation over plus and minus sixty degrees from the neutral position between the poles. Positioning one pair of magnetic field sensors around the magnet enables provision of a voltage signal that is proportional to the angular position and/or speed of the shaft through 120 degrees of rotation. Placing three pairs of magnetic field sensors around the magnet with 120-degrees of spacing provides three linear sensor output segments, each with a useful range of 120-degrees of shaft rotation.
