The deformable mirror used in adaptive optics can instantly correct the static wavefront aberrations and atmospheric turbulence wavefront disturbances of the optical system by changing its surface. This enables the optical system to automatically adapt to changes in the environment and maintain optimal performance. It is widely used in high-resolution astronomical observations, laser atmospheric t...

The air bags and particles trapped in the ice tell scientists what the atmosphere used to be like. This has aroused great interest among paleoclimatologists in glacier ice cores.By regularly sampling the ice core at its depth, they can reco...
