Abstract
Real-time correction of an optically aberrated wave front by use of a 10 x 10 ferroelectric liquid-crystal spatial light modulator as the co rrection device and a point-diffraction interferometer as the wave-fro nt sensor is demonstrated. This type of interferometer requires no ref erence arm and so can be used, in theory, in an astronomical adaptive- optics system. We discuss some of the unusual features of the point-di ffraction interferometer for wave-front sensing. (C) 1998 Optical Soci ety of America.
