Hello Everybody,
I want to get expert opinions about how we can find/measure the position of a few millisecond long laser spot on an A4 size of target area.
Although my application notting to do with shooting, using the "laser target shooting" analogy will help. In these days we can buy small red laser diodes just for few dolars. Assume we have one of them. The Laser diode will be connected to a microcontroller which will trigger (turn on and off for few millisecond) the diode. (If required, I think we can also modulate the laser diode for few KHz ).
We will point this laser and trigger to a target area of approximatelly
20x30 cm in size and at a distance of 25-50meters. Now the question; on the target, how we can find the position of this laser spot?I know there are some laser shooting targets which practically doing this. How they work?
Thx.
