Abstract
The paper describes a technique to simultaneously measure the tilt angles of the induction coil used in the watt balance experiment and correct its position from the Abbe offset error. The same three laser interferometers placed on the induction coil to determine the vertical position are also used for angular measures. An optimization algorithm is tested that allow a better estimation and correction of the Abbe offset error.
