Figure 7 This drawing shows four different letters on four different planes.

Figure 7A Shows one would get a blurred image to those letters if a picture were taken from the top of the object going from plane A to plane D.

Figure 7B Shows how linear tomography allows one to take a picture of the letter on the third plane while totally blurring out the letters on the other three planes.
