← ScienceWhich disruptive outcome develops during endoscopic imaging when multiple fiber cores transmit out of phase?
A)Speckle pattern limits image resolution✓
B)Chromatic aberration distorts color fidelity
C)Fresnel diffraction enhances edge contrast
D)Brewster angle diminishes glare artifacts
💡 Explanation
Speckle patterns occur because multiple, slightly delayed waves undergo constructive and destructive interference. This occurs because the separate cores introduce random phase shifts; therefore a grainy speckle arises rather than a clear image reproduction since coherent wave superposition fails.
