Project Description

Consultation will be performed during a visit of two representatives of DZHM in Length Laboratory of GUM.

The following topics will be discussed:

• modification and automation of the Kösters interferometer,
• calibration of gauge blocks with Kösters interferometer by optical interferometry with the phase-stepping method of exact fractions and phase-stepping method,
• facilities of Length and Angle Department
