Figure 67. Shadow on tomogram, grab and drag towards right side
Horizontal line in fundus preview window relates to left part of scan preview window. This scan
also should be horizontal. In the case here above the tomogram should be dragged right (head
movement device should be moved right to align scan and remove shadow.
The easiest way to align the tomograms is to drag a tomogram to the proper position.
If it is required to manually align working position across the center of the pupil, move first the
scanning head (usually forward) to working distance. At the working distance images created
from two preview cameras create one equal view. Then click on the pupil or use up/dw and
right/left movements to place the white cross in the center of equally aligned pupil.
