Figure 5.

Comparison of motion-corrected volumes acquired at 128 kHz and 250 kHz A-scan rates. A 6 mm × 6 mm macular volume of a healthy eye was acquired using 500 × 500 raster scans at 128 kHz A-scan rate and 720 × 720 raster scans at 250 kHz A-scan rate, respectively. Acquisition times per scan were 2.3 seconds at 128 kHz and 2.4 seconds at 250 kHz. Slower A-scan rates have high signal to noise, whereas high A-scan rates enable denser transverse sampling improving en face image resolution. Scale bars: 250 µm.
