	I need to compute the modular transfer function of a digitizing 
system. This value (the fourier spectrun of the response of the digitizing
system to an impulse signal) provides some handle on the sharpness of the
digitizing system. This is useful in finding out whether the lens based 2D
digitizer provide sufficient sharpness.

	Questions:
1. Any suggestion on how to compute the MTF and what's the procedure (I 
	want the MTF of the scanner, not the MTF of the display/hardcopy)
2. Any other measurement one might use to measure the sensor sharpness?

	Thank you.
