Abstract: Metrology management is the important technology base of the quality management system for the weaponry development. Metrology is a effective means to control quality and quality is the aim of the metrology. Safeguard function of the metrology on development of weapon systems are mainly embodied in two aspects:one is to supply metrology service for development of weapon systems, the other is to develop the universal calibration and measurement facility for weapon systems. The significant function and status of metrology service for calibrating the optical systems in weapon systems and for developing the national toplevel standards are expounded. The requirement for optical metrology that is associated with arm model development during “eleventh fiveyearprogram” is brought forward in this paper.The aim and orientation of metrology service and its management for optical systems in weapon equipments are proposed.
