[di′frak·təd ′wāv]
(physics)
A wave whose front has been changed in direction by an obstacle or other nonhomogeneity in a medium, other than by reflection or refraction.

On the right side of this equation, the first item is the spectrum of the zero-order diffracted wave, the second is the spectrum of the object wave which is modulated by the reference wave and translated to the point (-[[theta].sub.x]/T, -[[theta].sub.y]/T) relative to the center of the spectrum plane, and the third is the spectrum of the conjugate object wave.
