| Candidate lamps for high-repetition-rate systems have often
been evaluated with a single-frame digital camera to test for exposure and lighting uniformity. A simple trigger module that incorporates a delay synchronizes the flash with the camera shutter (typically 1/125 s).
To test the ability to freeze motion, multiflash pictures at 1000 fps have also
been taken, as illustrated by the picture of a rat trap in operation (Fig. 1). For the limited
number of pulses in a typical multiflash picture, even faster repetition rates are feasible.
With the reduced energy requirements for the limited number of pulses, a compact system can be
integrated with commercial single-frame digital cameras and an adjustable trigger/pulse
generator to provide a user-friendly multiflash system.
Please let us know: Would you have a need for an integrated system such as this? Would you
prefer a simple, inexpensive camera, which would have to trigger the event, or a more expensive
camera capable of responding quickly to an external signal?
