Investigation on interference-type moire deflectometry

Zhaoshu Liao, Ru-Shou Lu, Jingguang Tao, Yang Kun-tao

Abstract

A moire deflectometry without the Talbot effect is presented. A grating is replaced by interference fringes to overcome the inability of the Talbot pitch to change continuously. An additive type and a multiplicative type of moire deflectometry are described. The theory is analysed and the features are discussed with examples.
