TRIGGERED
RECORDING
ACOUSTICAL
Suppose you want to record a bullet as it leaves a gun. Usually
there is a loud sound when the gun is fired. You could use this
sound to trigger the Processor.
Place a microphone near the gun. Amplify and condition the
output of the microphone to be used as a trigger signal.
You will have to select the RECORD TRIGGER mode and set the
TRIG number so that the bullet is in front of the Imager during
the recording session.
If the event you wish to study makes a flash of light, makes a
loud noise or closes a switch, there is hardware readily available
to convert these physical events into electrical signals. There are
also sensors available that will generate a suitable trigger signal
each time an object moves past the sensor. There are sensors
that react to changes in air pressure or a change
in motion. The possibilities are endless.
