SECTR lateral resolution characterization. (a) En face OCT volume projection and magnified region showing contrast cross-section (inset) of group 4, element 6 (arrow, 35 μm). (b), (c) Two SER images were acquired at offset image planes to compensate for slight astigmatism at the focus. SER images and contrast cross-sections with the (b) spectrally-encoded and (c) scanned dimensions in focus showing group 4, element 5 (arrow, 39 μm) and group 5, element 2 (arrow, 28 μm), respectively. Anisotropic SER lateral resolution is a result of dominant chromatic aberration.
