Speeds are faster, but golf simulators use radar to determine velocity, and position of a golf ball. Newer simulators use two cameras and strobe lights, with a specially marked ball, and capture spin in addition to velocity and position. In a single camera frame flick the strobe once if you merely need position (you'll need a trigger for the strobe, but knowing the approximate velocity of the bullet you can use sound, otherwise there are a variety of light curtains and other methods to trigger the strobes) If you want velocity (though at a target range you shouldn't need it) then you flick the strobe twice and compare the movement in the single captured frame. You can use IR strobes and cameras if you don't want to blind the participants, though a good directed strobe and a black target shouldn't cause issues. -Adam On Mon, Apr 14, 2008 at 9:34 PM, Vic Fraenckel wrote: > Several of us have been speculating on how to go about designing a target > system for a rifle range that did not use paper targets.
