title: Analysis of the Lau effect using Walsh functions.
abstract: An experiment similar to the Lau effect but employing the Walsh functions as diffracting apertures is performed. The equivalent resonance condition and the corresponding intensity light distribution are derived. This approach is used to implement a spatial-filtering optical device.
