Advanced Noise Analysis and Design Techniques for LIGO | sasd

Innovative Noise Analysis Solutions

We specialize in advanced noise analysis using a four-phase design to enhance data accuracy and reliability in gravitational wave detection.

A room with a grid-patterned wall that resembles an anechoic chamber, containing various electronic equipment. There is a large antenna-like structure in the middle and several cables running across the floor connected to a control panel or server rack. Blue absorptive materials are placed around the antenna setup for sound or signal management. A stack of red crates and a cardboard box are in the background.
