Abstract
A discrete sampling method in optical transformation has been suggested in this article. Based on the consideration of unitary transformation, that is important for opcical transformation, conditions of sampling an optical system are obtained. The expression of propagation matrix including the effect caused by the width of sampling window is derived. As an example, the distributions of holographic amplitude and phase calculated by designing a given Walsh transformation are given.
