← ScienceWhich consequence results when temporal coherence decreases within laser-based distance ranging systems?
A)Signal reflection increases dramatically
B)Measurement resolution degrades substantially✓
C)Power consumption reduces by half
D)Beam divergence increases rapidly
💡 Explanation
Reduced temporal coherence diminishes the achievable resolution because interference fringes become less distinct, therefore range precision worsens rather than alternative effects on power, reflection, or divergence, under these defined conditions. The contributing mechanism is interference.
