Remote Internal Diameter Measurement of Ring Gauge Based on a Low-Coherence Tandem Scheme

Abstract:

A novel internal diameter measurement method based on a low-coherence tandem scheme is firstly demonstrated. From operational analysis, it is understood that a low-coherence tandem scheme can be served for internal diameter evaluation by using a combination of a transmission grating and a ring gauge instead of a classical Michelson interferometer to store and transmit the internal diameter information. As a result of the experiment, in the present experimental environment, diameter measurement of several millimetres with a relative standard uncertainty of several micrometres was performed. Taken together, these results suggest that the present measurement method is expected to be used as a powerful remote internal diameter calibration tool for next-generation calibration network systems.
