Yep, those guns depend on the fact that a CRT really only has one dot lit at any given moment. Compare the time when the gun got its pulse of light to the beginning of the video frame, and you know where the gun was pointed. Earlier, simpler ones just detected light. You could point those ones at score numbers or other objects on screen and get credit for hitting the 'target'.
