Moiré Fringes Poem by J Sheba Anandhi

Due to difference in phase
Contrast can eventually arise
In an image that's been taken
Employing a vital instrument,
The results of characterization
Can give detailed information
On what is basically present,
The shift by a small amount
Depends on the deviation parameter,
Taking the fringes into account,
They aren't direct images of the structure,
Lattice fringes can give information
On the existing lattice spacing,
Interference of lattice fringes
That is formed by translation or rotation
Is typically called as moiré fringes,
To discard the erroneous information
Discern moiré fringes from lattice fringes.
