Which risk increases significantly when crossed polarizers insufficiently block transmission?

A)Reduced contrast ratio in displays
B)Excitation of rogue lasing modes
C)Increased material chromatic aberration
D)Worsening of signal group velocity

💡 Explanation

Leakage through imperfect polarizers allows some light to transmit because polarization vectors are not perfectly orthogonal; therefore, the image contrast decreases, rather than causing lasing or chromatic issues, which arise from wavelength impairments.
