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 correction device and a point-diffraction interferometer as the wave-front sensor is demonstrated. This type of interferometer requires no reference arm and so can be used, in theory, in an astronomical adaptive-optics system. We discuss some of the unusual features of the point-diffraction interferometer for wave-front sensing.

摘要

演示了使用10×10铁电液晶空间光调制器作为校正装置以及点衍射干涉仪作为波前传感器对光学像差波前进行实时校正。这种类型的干涉仪不需要参考臂，因此理论上可用于天文自适应光学系统。我们讨论了用于波前传感的点衍射干涉仪的一些独特特性。
