Abstract
Moire fringes are visually observed when two 2-D implicit grids are superposed and rotated. We introduce two innovations in the broad field of moiré. The first calls attention to hidden or implicit grids from the photocopying process that are also used to produce moire patterns. This method of moire pattern production is extended to hidden grids optoelectronically generated by digitizing TV-CCD images. Our second innovation is a proposed application of this type of moire pattern to measure distances.
