Laser Interferometry & Detector Design: Structures & Vocabulary

Ground-based gravitational-wave observatories such as LIGO use laser interferometry to measure fractional changes in arm length far smaller than the diameter of a proton. Interferometer design determines the detectable gravitational-wave frequency range and sensitivity to compact binaries.
