Abstract: | Traceability of angle measurements is based mainly on the standard of the plane angle –
prism (polygon) calibrated at appropriate accuracy. Nevertheless, the standard (etalon)
of flat angle – polygon has many restrictions for the transfer of angle unit – radian (rad)
and other units of angle. It depends on number of angles formed by the flat sides of the
polygon. Here is proposed a possibility to create the standard of the plane angle equal to
p rad using the circular scale with the rotation axis of very high accuracy and two opposite
placed precision reading instruments with appropriate alignment. Proposed method permits an implementation of p rad as primary standard angle and enables to assure a traceability of flat angle measurements at laboratory environment. Short information about the
multipurpose angle measurement test bench developed is presented. |
