• As the means for measuring the surface contour of a three-dimensional uneven object by the moire method are known the oblique shadow method using collimated light beams and the modified method utilizing divergent light rays emanated from a point light source. The former method facilitates the accurate measurement of the surface contour of a measuring object. On the contrary, the latter method gives an approximate surface contour. In spite of the above mentioned drawback, the latter method has been used widely for the measurement of the surface contour of a large uneven object up to this day. In this paper, an accurate theory for the latter method is proposed. Also a procedure for determining the applicable limit of the latter method is presented.
