... recommend that you find a ripple tank to play with if at all possible. In the meantime, we will have to depend on a simpler optical demonstration of the same effects. Luckily, we can see most of the relevant phenomena almost as clearly with moiré fringe patterns. We can think of a pattern of concen ...

Relativistic Corrections in Displacement Measuring Interferometry

Let us assume that the mask pattern is projected onto a wafer at four-fold reduction. This requires that the reticle stage moves in a highly synchronized manner with the ...
