B) interferometry.
C) refraction.
D) signal processing.

Question

Quizplus · Accepted Answer

Interferometry is the practice of combining signals from two or more reflectors to achieve better angular resolution. It allows for more precise measurement and imaging of distant objects, such as in radio astronomy or medical imaging. Adaptive optics, refraction, and signal processing are all related techniques, but do not involve the combination of multiple reflectors in the same way as interferometry.
