Buchta Z, Reřucha S, Mikel B, Cížek M, Lazar J, Cíp O - Sensors (Basel) (2012)

Bottom Line: An experimental setup combines Dowell interferometer and Michelson interferometer to ensure a gauge block length determination with direct traceability to the primary length standard.By monitoring both gauge block sides with a digital camera gauge block 3D surface measurements are possible too.The principle presented is protected by the Czech national patent No. 302948.

ABSTRACT
In this paper, a novel principle of contactless gauge block calibration is presented. The principle of contactless gauge block calibration combines low-coherence interferometry and laser interferometry. An experimental setup combines Dowell interferometer and Michelson interferometer to ensure a gauge block length determination with direct traceability to the primary length standard. By monitoring both gauge block sides with a digital camera gauge block 3D surface measurements are possible too. The principle presented is protected by the Czech national patent No. 302948.

f3-sensors-12-03350: The Interference Detecting Signal (IDS) recorded during a pilot experiment with gauge block measurement. In the case shown in this figure, a gauge block with the length 17 mm was measured.

Mentions: For illustration, an interference detecting signal (IDS) record is shown in Figure 3. The signal was recorded during a pilot gauge block measurement experiment and it represents a correlation coefficient value resulting from a comparison of two sequential samples of the output beam intensity. In the designed system, this signal is used for an automatic detection of the measuring positions. In the case shown in Figure 3, a gauge block with the length 17 mm was measured.
