New Adaptive Optics Technology Boosts Gravitational Wave Detectors
Physicists at the University of California Riverside, US, have developed a new system called FROSTI (FROnt Surface Type Irradiator) to compensate for temperature changes in optical components.
This technology will enable future versions of the Laser Interferometer Gravitational Wave Observatory (LIGO) to run at higher laser powers, reducing noise and expanding capabilities.
With FROSTI, next-generation machines will be able to detect gravitational waves emitted when the universe was just 0.1% of its current age, before the first stars had even formed.
Gravitational waves are
distortions in spacetime that occur when massive astronomical objects accelerate and collide.
