Moire Fringes
- A pattern formed by the interference between two regular sets of divisions.
- Parallel Pattern
- where
- dm = Moire fringe spacing [m]
- d1 = grating 1 spacing [m]
- d2 = grating 2 spacing [m]
- d1 = grating 1 spacing [m]
- Rotated Pattern
- where
- dm = Moire fringe spacing [m]
- d = grating spacing [m]
- θ = relative rotation angle between gratings where -π/2≤θ≤π/2
- d = grating spacing [m]
