I am actually a mechanical engineering student and fairly new to circuits.
For my graduation project, I am building a test-setup in which we use a camera setup. To avoid having to use a high speed camera, we are looking into two exposures per frame to do PTV.
For that reason I looked into high power led-modules and am looking into a circuit that makes the LEDs flash at a clearly defined interval at a clearly defined speed.
Furthermore the circuit must accept trigger signals to be able to synchronise the camera. The camera sends out a pulse every time it takes a shot.
The pulses I need are of 0.1-1 ms and the times between the pulses in the same order, but always larger. I found the circuit posted below for the astable oscillator that puts out such a signal.
I found out the following project for driving high power LEDs http://forum.allaboutcircuits.com/showthread.php?t=32364.
I am now wondering whether I can actually switch the LEDs that quickly. And I furthermore wonder how should I incorporate the triggering?
