Projection method of resolving ambiguities by determining the order of colors in moiré fringes

Not Accessible

Your library or personal account may give you access

Abstract

From the scientific literature there are some well-known methods used to resolve the arising problem of ambiguities in moiré patterns. The main disadvantage of these methods is that for image processing one must use several patterns. It means that it is impossible to work with dynamic objects in a real-time operation mode. We present a projection method to resolve ambiguities by determining the order of colors in moiré patterns. This method is based on the application of color rulings to gratings in a projection moiré technique.
