Which outcome occurs when the coherence length dramatically decreases in a confocal microscope laser source?

💡 Explanation

Decreased source coherence will degrade axial resolution because constructive interference weakens for longer optical path differences due to autocorrelation range. Therefore, axial slices become blurred, rather than better defined, because path variations obscure interference.
