Fig. 5.

Original (first column) and computationally refocused (second column) en face porcine triceps brachii muscle images. The images are extracted from a depth away from the depth of focus. The first to third columns are the intensity, birefringence, and DOPU images, respectively. (g)-(l) are corresponding magnified images of the regions outlined by black-dashed boxes, where the left images are without refocusing and the right ones are with computational refocusing. Red arrows in (a) and (b) denote a hollow region, which exhibits evident sharpening following computational refocusing. Black arrowheads in (i) and (k) denote birefringence and DOPU artifacts. Scale bar denotes 500 μm.
