Smart Industry and Society System Using Compact and Unique Optical Frequency Combs

Abstract

Hirokazu Matsumoto

Optical frequency comb is very useful as high accuracy metrology tools in the many industrial production fields. However, it is important that the tools are simple, easy and low- cost, moreover they are required to be traceable to international measurement standards.

In this paper, unique optical frequency combs with simple and stable functions are developed. The beat frequencies of two combs are evaluated on the stability and accuracy of the comb. The unique distance measurement method is developed which is possible the absolute distance with high resolution, high accuracy. Finally, this optical comb system is discussed for next social life system.
