Novel principle of contactless gauge block calibration.

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.

f2-sensors-12-03350: Sketch of the screenshot recorded by the CCD camera.

Mentions: Figure 2 shows a sketch of a screenshot recorded by the CCD camera. There are two interference areas—the beams in the area no. 1 interfere in reference surface positions P2′ and P3′ and in the area no. 2, the beams interfere in reference surface position P1′. During a gauge block measurement procedure, only the interference signal from the relevant area of interference is recorded. The recorded data are used for complex gauge block analysis, namely gauge block length measurement, gauge block face surface measurement and for interference fringe shape analysis to evaluate the gauge block flatness distortion.
