Method of image fusion. The thin dased line represents the DC line which is located at the middle of the images. The maximum sensitivity (bright background) is shown around the DC and then fades (gray background) due to fall-off. The upper part of (a) within the thick dashed-line region of interest was concatenated with the lower part of (b) within the region of interest to form the final image (c). δ× is the offset between the two reference arms. The −6dB effective imaging range is labeled in each image.
