SUMMARY

The Moire effect arises from the superposition of two patterns, which can be attributed to both light interference and shadow effects. While the phenomenon is commonly observed in large-scale objects, such as rows of trees or railings, the interference aspect becomes significant when the spacing of the patterns approaches the wavelength of the observed radiation. For a deeper understanding of the Moire effect, "The Theory of the Moire Phenomenon" by Isaac Amidror is a recommended resource.

PREREQUISITES
  • Understanding of light interference principles
  • Familiarity with shadow effects in visual perception
  • Knowledge of pattern recognition techniques
  • Basic concepts of wave physics
NEXT STEPS
  • Research light interference patterns in physics
  • Explore shadow effects in visual arts and design
  • Study the mathematical modeling of patterns
  • Read "The Theory of the Moire Phenomenon" by Isaac Amidror
USEFUL FOR

Students of physics, visual artists, graphic designers, and anyone interested in the optical phenomena related to pattern interactions.

Hello,

I am studying the Moire effect and I have a question about it: the appearance of fringes because of the superpostion of two grades is the effect of light interferance or simple the superpostion of shadows?
And does anyone know how can I go about to determine what will be the pattern given to grades? Thank you

You can see the moire effect even with very large scale objects, such as two rows of regularly spaced trees, one behind the other, or railings on a bridge, so I don't think it is just an interference effect. On these large scale objects it is a shadow effect. Interference may come into play as the spacing of the gaps becomes smaller - approaching a few wavelengths of the radiation the moire effect is being observed with.
 
Thank you very much. Just for reference to whoever is looking at this thread, I found a nice book on this topic: The Theory of the Moire Phenomenon, by Isaac Amidror.
