3D SHAPES MEASUREMENT SYSTEM USING AN OPTICAL MODULATOR

K. Tsujioka, H. Furuhashi, Y. Uchida

Abstract

We have continued research on 3D shapes measurement system using spatial modulator. The advantages of this system are non-contact, non-invasive, and short time measurement. We proposed a method using differentiation to expand the measurable area and improve the accuracy of measurement. Additionally, We proposed to eliminate the influence of marking on target object surface. It was a very practical and effective method.
