Abstract

The modern Hartmann sensor provides a geometric measurement of wavefront as opposed to an interferometric measurement. Thus, it is free of some of the constraints of interferometry such as the requirements for vibration isolation, source coherence, and a reference source. Hartmann sensor configurations are presented which demonstrate the versatility of this technique while providing wavefront evaluation accuracy and sensitivity comparable to interferometry. There is a discussion of system alignment and operation as well as a discussion of software requirements.
