Earth's atmosphere blurs and distorts light from astronomical images. In order to correct these distorting effects, astronomers have developed adaptive optics, a system which senses the incoming light and mechanically corrects for the distortions. This article describes an experimental setup to test a kind of adaptive optics system in a laboratory, helping to advance this important field.
