Abstract

This paper summarizes a principle for measurement of inner diameter or profile of pipes and tubes using optical method. Based on this principle, compact probes have been developed for industrial applications such as car industry, heavy industry and civil engineering. In addition to large probes for pipes, tubes and tank-like objects with diameter larger than 1meter, such small size probes as 5mm ∼25 mm in diameter has been produced including prototypes and commercialized products. We report availability and utility of our principle and probes we developed with some experimental results.
