Four high speed serial fiber optic data links connect the system to the computer. It can be triggered externally by light or electrical input. This system enables shutter speeds down to 3 ns, which allows sharp images even of very fast movements. (Source: PCO)
In combination with the narrow-band Pulsed Diode Laser Light Source CAVILUX SMART and the use of the appropriate optical bandpass filter, intense process glare (e.g. the arc of light of fusion welding processes) can be outshined in a very narrow wavelength range and thus are blanked out from the image.
The optics distributes the image to each of the four channels of the camera. Each channel has its own image intensifier. This module works similar to a low-light amplifier: The light flux is first converted to an electron flux by the photoelectric effect. It is then amplified by the microchannel plate and finally lights a fluorescent screen. This screen is filmed by a CCD camera. (Source: PCO)
