This is how the GunCon (Time Crisis) gun worked -- comparing the observed beam refresh with a feed of the video signal. Unfortunately, this method requires a CRT, so these guns don't work with LCD or plasma displays. That's why modern light guns, like the GunCon 3, use a Wii-like system that triangulates position based on infrared LEDs attached to the display. http://en.wikipedia.org/wiki/Light_gun#Cathode_ray_timing http://en.wikipedia.org/wiki/Light_gun#Cathode_ray_timing
