Which result occurs when limited spatial coherence is applied while forming an image under extreme microscopy conditions?

A)Reduced diffraction limited spot size

B)Speckle contrast is visibly increased✓

C)Deeper tissue penetration depth

D)Increased signal to noise ratio

💡 Explanation

Speckle contrast is heightened because limited spatial coherence implies that wavefronts arrive with phase differences, so constructive and destructive interference amplifies intensity variations rather than averaging them. Therefore speckled images result, rather than a clear transmission image from spatial average.
