Flame Penetration Imaging
Flame penetration imaging is a technique which can be used to take movies through flames, arcs and explosions. It can be
used whenever there is a very bright subject and a darker subject to be imaged.

 |
 |
| Conventional high speed movie of firework. Flame
is over-exposed (white) and unburned region is under-exposed (black) |
VisiBrite movie of same firework. Note that the flame has disappeared,
and we can clearly see the melting process. |
Applications
- Circuit breaker contact erosion
- Laser welding visualization
- Arc welding
- Aero-engine blade breaks
- Metal arc sprays
- Explosions

How it works
The VisiBrite system uses a laser to illuminate the subject with high
brightness, narrow bandwidth light. The system's specially modified, digital
high speed camera then only accepts the laser light and rejects the broad-band
light emitted by the subject under study. This allows the camera to 'see'
through plasmas, arcs, flames and explosions to record details of processes
which would otherwise be totally obscured by the background light.
Product selection matrix
For all systems listed below, laser exposure time is 30 ns or less. This is fast enough
to freeze bullets in flight. Other configurations are available - for more information
