← ScienceWhich risk arises when an interferometric gravitational wave detector underestimates mirror surface curvature?
A)Reduced detector resonance frequency sensitivity
B)Increased thermal lensing aberrations effects✓
C)Vacuum system leakage intensifies rapidly
D)Increased seismic noise displacement errors
💡 Explanation
Increased thermal gradients will create thermal lensing because nonuniform heat induces a refractive index change within the mirror based on prior variation in curvature, resulting in blurred or distorted signal rather than high focusing. Interferometers calibrate to predicted curvature.
