No, no, integration time is not a function of computers. It's a
measure of how many independent samples it takes to form a coherent image.
It's a function of wavelength. The longer the wavelength, the more
samples you need the more time it takes to illuminate the target. We can
do the math in realtime with computers now, but physics is hard to get
around.
