With Fig. 13.31 in mind, show that the transverse magnification of the system is given by -fi/fi and draw the appropriate ray diagram. Draw a ray up through the center of the first lens at an angle 6 with the axis. From the point where that ray intersects Σt draw a ray downward that passes through the center of the second lens at an angle . Prove that. Using the notion of spatial frequency, from Eq. (11.64), show that k1 at the object plane is related to k, at the image plane by

What docs this mean with respect to the size of the image which fi > f1? What can then be said about the spatial periods of the input data as compared with the image output?
