The VisiBrite systems use lasers to illuminate the subject with high brightness, narrow bandwidth light. The imaging 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.
One important area of study is welding. The glare from an arc weld or the fireball of a laser welding process is impenetrable for most imaging systems. Derivatives of the VisiBrite range have been developed specifically for use in weld imaging. Specially selected and modified cameras and laser illuminators are combined to form extremely powerful VisiWeld, weld viewing systems, with frame rates from 60 fps to 1,000 fps. These powerful visualization tools enable flows within the weld pool to be studied.
