Methods of inspecting hole diameters with optical probes

  • Published:
Measurement Techniques Aims and scope

Conclusions

  1. 1.

    Contactless methods of measuring hole diameters with one optical probe (perflectometer) can reduce the measurement error for small hole diameters (0.2–40 mm) to within ±1.4–1.9 μ.

  2. 2.

    Contactless methods of measuring hole diameters with two optical probes have the advantage of relative measurement and can reduce the error in measuring hole diameters to ±2 μ.
