    • note
    • The purpose of a diversity function in wavefront sensing is to "spread-out" out the optical response to expose aberration information. Since defocus has only angular dependence, no one part of the point spread function is emphasized more than any other.

    • "Edge weighting" is also an effective technique based on the area of pixel coverage along a segment edge. We thank Rick Lyon, Jim Fienup, and Matt Bolcar for helpful discussion.

    • The un-stacked image data shown in Fig. 10 corresponds to the negatively defocused image of the pair. Defocus was obtained by moving the secondary mirror by ± 200 microns. Eventually, diversity defocus will be implemented using weakly powered fixed-lenses inserted into the trunk circuit beam, as baselined for NIRCam on JWST.

    • Under-sampled in this context means that the ratio: (f/# ×λ.) / (detector pixel size) is less than 2. In such cases we are below the Nyquist sampling rate and the ratio of image-plane sampling to the pupil sampling must now be greater than a factor of two to avoid aliasing in the FFT.

    • The flight deployed Hubble pupil image was not available but had to be estimated using a few iterations of the iterative transform method. Details are discussed in the literature. Details are discussed in the literature; see Ref. 25.
