%X This paper presents a method to measure the three dimensional displacement field, the in-plane and the out-of-plane conponents, by partially coherent light Moire interfer-rometry. It needs simple optical set-up and low demand on vibration isolation, and is valid for the measurement of the displacements on the sarface of engineering structures.The related formulas are derived by the theories of wave-front inteference and Fourir op-ties. The in-plane (v0 v45, v90) and the out-of-plane(w) displacement fields are obtained simultaneously from either transparent or opaque specimens of which the test data agree well with the theoretical ones.
