Abstract

The LIGO detectors are a technological marvel, the culmination of ~50 years of research and development, that have opened up a new window on the universe by making the first detections of gravitational waves. The LIGO detectors can measure strain caused by gravitational wave perturbations down to 10-23 (at their most sensitive frequency band). In this talk, I will give an overview of the techniques that have allowed us to reach such incredible precision, and where possible relate said techniques to the field of acoustics.
