I have an NI9401 in a 9174 chassis. I would like to measure the velocity of a bullet. I have 2 optical sensors, each that put out a 5V pulse when the bullet passes thru the beam. The only input should be distance between sensors and units (ft or m) and the output should be time in seconds and velocity in either feet or meters per second. This should be about as simple as it gets. I've been looking for an example .vi and haven't been able to find one yet.
