Abstract
The apparatus includes a light source for directing a measuring beam toward a workpiece and a photo detector positioned to receive a portion of the measuring beam reflected from the workpiece. A beam splitter is positioned between the light source and the workpiece to reflect a portion of the light source measuring beam to a monitor photo detector. The monitor photo detector receives the beam splitter reflected beam and provides an output signal representative of the position of the beam splitter reflected beam, and hence, the position of the light source with respect to an idealized position. In one embodiment, the photo detector develops a monitor output signal representative of the deviation between an Idealized Centerline and an Actual Centerline of the light source. The monitor output signal may be employed for display purposes. The monitor output signal may also be employed with positioning means to displace the light source from its actual position toward the ideal position so as to reduce the measurement error associated with the actual position of the light source. Also, the monitor output signal may be employed to develop a compensating signal for reducing the measurement error associated with the actual position of the light source.
