Abstract

This paper discusses the geometrical relationship between a two dimensional grid of lines and an illuminated screen pixelation and the Non-Moire spatial interference pattern that arise from their interaction. In our case we have a two dimensional pixelation of illumination at the screen. We have a two dimensional EMI (Electro Magnetic Interference) mesh grid (horizontal and vertical wires (thickness = 0.0012 inches) at 90 degrees to each other with 50 openings per inch (opi),80 opi and 100 opi); this mesh can be oriented at some angle of the horizontal wires of the mesh to the pixelation of the screen. This creates a spatial interference pattern which is different from that of a traditional Moire pattern.
