title: Moire pattern resulting from superposition of two zone plates.
abstract: The moiré pattern resulting from superposition of two zone plates is analyzed in a general manner. Characteristics of the moiré pattern and hence its reconstructed ghost images are so tabulated that visualization is made easier. Experiments are performed to substantiate the theoretical predictions, and their results show perfect agreement.
