Lattice-based screen design for N-color all-orders moire-free screen set

摘要

A method and system to generate a moiré-free to all-orders N-color screen-set by a lattice-based screen design the method including choosing a lattice in frequency space with basis vectors u1 and u2 such that (∥︀{right arrow over (u)}1∥︀,∥︀{right arrow over (u)}2∥︀,∥︀{right arrow over (u)}1±{right arrow over (u)}2∥︀)>f min, where f min is the minimum moiré invisible to the human eye, and choosing a set of N pairs of fundamental frequency vectors on the vertices of this lattice to be the screen vectors.
