METHHOD AND SYSTEM FOR SENSING AND ANALYZING A WAVEFRONT OF AN OPTICALLY TRANSMISSIVE SYSTEM

摘要

An enhanced dynamic range wavefront sensing system (100) includes a light source (110) disposed on a first side of an optically transmissive device (140), a wavefront sensor (180) disposed on a second side of an optically transmissive device, a relay imaging system (150, 170) disposed between the optically transmissive device and the wavefront sensor, and means for adjusting a distance between the light source and the optically transmissive device (120). Beneficially, the relay imaging system includes a range-limiting aperture (160) to insure that the wavefront sensor never goes out of range so that a feedback system (190) can be employed to move the light source one focal length away from the optically transmissive device.
