← ScienceWhich risk increases when coherence degrades within LADAR systems?
A)Reduced signal-to-noise ratio✓
B)Increased laser power consumption
C)Elevated detector array temperature
D)Compromised material refractive coefficient
💡 Explanation
A loss of coherence increases noise. This is because the interference fringes weaken through *temporal defocusing* becoming indistinct causing fewer photons constructively interfere; therefore the signal is overwhelmed by background noise, rather than increased temperature.
