Abstract

Quartz Control Plates used as standards for the quality control of polarimetric and saccharimetric measurements have to be calibrated with low uncertainty. A set-up for this is operated at PTB, and INMETRO is building a similar one. In both set-ups, the null detection of the polarimetric signal is of high importance. A novel procedure for this is proposed and tested which avoids the use of an electronic feedback loop.
