| description | Non-contact sensors are becoming an increasingly popular tool for use in dimensional
measurement, inspection and quality control. However, there exist a number of challenges
associated with the use of these non-contact sensors in dimensional inspection systems.
One important challenge is to understand the associated measurement errors and determine
the objective accuracy of such an inspection system. This paper examines the effect of
misalignment and scanning methodology on the measurement accuracy of a non-contact
dimensional inspection system. It is important to understand this topic since the majority
of optical sensor manufacturers do not supply information about the alignment between the
optical line of sight and the mechanical interface of the sensor or measurement system. We
prove the evidence of this measurement error through both experimental results and
simulation. Finally, by using a constant standoff measurement method we succeeded to show
that the majority of inherent misalignment error can be eliminated. |
