Paper Abstract

A 3-D displacement general equation of moire interferometry for measuring 3-D displacement of the negative camber using a dual columnar light wave is put forward. The authors researched the interference field of the dual columnar light wave and its change over law, and they deduced the internal columnar round and axial and radial displacement equation for measuring them. Using an optical fiber for flexible transmission and a small volume columnar lens system to realize miniaturization of the optical system, this technique can find use in measuring internal pipeline.
