The different ways of combining optical patterns with spatial periodicities are examined. The characteristics of and differences between additive, subtractive, and multiplicative pattern superposition are presented. The micro- and macro- (Moiré) structures in these cases are different. Examples are shown for two-pattern and multiple-pattern superpositions.
