Fig. 9.

Artifacts that appear at the periphery of the en face field. The raw data are identical to what appear in Fig. 6. The first-to-third columns show the computationally refocused en face intensity, birefringence, and DOPU images, respectively. For (a)-(c), zero-fields were padded to the periphery of the image before the first Fourier transform of the computational refocusing process. On the other hand, zero-padding was not applied for (d)-(f). The white insets are magnifications of the black-box regions. Arrows in (d)-(f) indicate artifacts at the periphery. This artifact can be removed by zero-padding. The scale bar denotes 500 μm.
