TLDR
In this article, the authors analyze the information that contains in colour moire fringes and estimate its effectiveness, and make device independent simulations for colour formation of one moire fringe in colour space by different conditions were made.Abstract:
Moire topographic technique is widely used for three-dimensional surface reconstruction. One of the main problems is determination of the absolute order of a fringe for finding the depth difference between two points in moire patterns, i. e. convex and concave surfaces distinction. Most solutions of the problem are very complicated; also they usually require several moire images. Application of colour-encoded gratings in projection moire method allows solving the problem simply and quickly. The authors analyze the information that contains in colour moire fringes and estimate its effectiveness. With this purpose device independent simulations for colour formation of one moire fringe in colour space by different conditions were made.read more

Modeling and empirical investigation of white light-color sampling moiré
TL;DR: The principle of color sampling moire is derived assuming that the Bayer pattern-CCD array can be considered a combination of a bicolor red-blue grating and a green smooth plate as mentioned in this paper.

Improved fringe carrier technique for unambiguous determination of holographically recorded displacements
TL;DR: In this paper, a linear phase carrier is introduced to eliminate the ambiguity in holographic fringe interpretation, which is based on generating a high density linear phase carriers. But the technique is not suitable for holographic interferometry.

Color Encoded Moire Contouring
TL;DR: The goal is to develop a means to obtain a one time snapshot of the part under inspection that gives all of the necessary information required to produce a contour, and work directed toward using color to improve existing contouring techniques is described.
