A novel nano-measurement system based on dual Fabry-Perot interferometer is designed and a mathematical model for various links of the system described. Considered with the characteristics that the mathematical model for the mutual action between probe and sample surface is complicated, a control system based on fuzzy control theory is designed. Some theoretical basis and practical measurement method for carrying out nano-measurement through control curve central line of probe vibration is proposed. Simulation experiments for the system are carried out on this basis. The experimental results fully demonstrate the correctness of system and theoretical basis.
