Fig. 3. — Magnitude of the Fourier transformed SLO frame. Colorbar displays log of the magnitude and spatial frequency is given in cycles per mm (a). High-pass filter indicating multiplication factor for each frequency - this is directly multiplied with the Fourier transformed reference image (b). Phase correlation peak between reference image and another SLO frame. The offset from the center point (coordinates indicated in X: and Y:) denotes the observed translation (in Pixel) between the scans. The peak can be clearly distinguished from the background noise (c).
