title: Analysis of the moiré effect by use of the Wigner distribution function.
abstract: The Wigner distribution function is used to analyze moiré patterns that originate from a superposition of nonperiodic masks. For patterns with well-defined local frequencies, the concept of the Wigner distribution function allows one to extend the description of the moiré effect in terms of vector sums. How this picture can be applied to design moiré patterns and to analyze their information content is also discussed.
