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.

f1-sensors-12-03350: Optical setup for gauge blocks measurement. CP1, CP2 and CP3 are compensating plates, RS is a reference surface, λ/4 is a retardation quarterwave plate.

Mentions: The presented optical setup combines a Michelson interferometer and a Dowell interferometer [11], placed in the reference arm of the Michelson interferometer. The principle of the measurement is illustrated in Figure 1. A parallel beam, generated by a white-light source, is divided into two parts by semireflecting mirror 1. The resulting measuring beam goes through a couple of compensating plates CP1 and CP2 and after that is reflected back by a reference surface RS.
