System for automatic gauge block length measurement optimized for secondary length metrology

The paper also presents in detail a set of optimization steps which have been done in order to transform the original experimental setup into the automatic system which meets secondary length metrology requirements. To prove the measurement traceability, we conducted a set of gauge block length measurement comparing data from the optimized system and the established reference systems TESA NPL A.G.I. 300 and TESA-UPC operated in Czech Metrology Institute Laboratory.
