Indirect Wavefront Measurement, Part I
Author Affiliations +
Abstract
This section will examine wavefront sensor schemes that measure either the local slope, dW/ˆ•dy (or dW/ˆ•dx), or the differential wavefront dW as a function of pupil coordinates. Recall that the former provides information like that contained in Fig. 2.8 (a); while the latter, like that contained in Fig. 2.9 (a).
