✦ Synopsis

A new type of moire experiment is presented. Each grating is synthesized by Walsh functions. These functions have the property of being cyclically periodic, and the resulting moire is also cyclically periodic. Gratings synthesized by different Walsh functions were employed and a contouring measurement is described.

## Walsh product matrix is formed by the multiplication of Wakh vector and its transpose. The operation of Walsh product matrix on a coefficient vector equals the product of a coefficient matrix and a Walsh vector. This unique property of Walsh functions is used to determine the unknown parameters o
