UC Riverside Researchers Use Thermal Cameras to Correct LIGO Mirror Distortions
Researchers at the University of California, Riverside, have developed a new technique combining infrared thermal imaging and computer models to measure and correct microscopic, heat-induced distortions on Laser Interferometer Gravitational-Wave Observatory mirrors. The method could increase the sensitivity of the upcoming LIGO A+ upgrade by 31 percent. Fixing an optical imperfection inside one of the … Read more
