Fig. 2.

Holographic reconstruction is shown for orthogonal (i.e., wide-field) illumination (a-d) and structured illumination imaging (e-h) before post-processing for enhanced resolution. (a,e) Raw interferograms at image plane are shown for orthogonal and structured illumination imaging and (b,f) associated Fourier spectra. In inset of (a) note the horizontal fringes from off-axis reference wave illumination, and in inset of (e) note overlapping horizontal fringes from off-axis reference wave illumination and vertical fringes from structured illumination (c,g) Digitally filtered and DC centered spectra from (b,f) and corresponding (d,h) inverse Fourier reconstructions are shown.
