ABSTRACT:
A laser-based multi-axis position measurement unit measures position deviations in 5 axes while traversing a 6th linear axis. The apparatus includes three components: 1) a laser-beam unit which emits two parallel laser beams; 2) a sensor unit including at least three laser-position sensors, one of them being transparent; and 3) a microprocessor or computer unit which converts X,Y laser position data from the three sensors to displacements in 5 axes: X (horizontal), Y (vertical), Pitch (angular motion about the X axis), Yaw (angular motion about the Y axis), and Roll (angular motion about the line of travel). Readout of the 6th axis, the line of travel, is provided by means of a separate linear transducer or laser-based ranging system. The device includes an arrangement of three digital sensors on two parallel laser beams to deduce position in 5 axes. Applications for the measurement unit exist in machine tool measurement and calibration, robotics, coordinate measurement machines, optical alignment and other areas where position in multiple axes must be determined. The position information may be directly displayed or used as input for a closed-loop positioning system.
