← ScienceWhich consequence results when applying common paints in laser interference lithography?
A)Reflected laser wavefront cancellation
B)Increased holographic diffraction efficiency
C)Reduction in spatial coherence length✓
D)Enhancement of polarization mode dispersion
💡 Explanation
Spatial coherence is disrupted by the paint's refractive index variations. This occurs because the paint's particles scatter light causing destructive interference, therefore the coherence length reduces rather than enhancing holographic effects because refractive index is not uniform.
