Strobe Output
Strobe output is used to activate a photo strobe at the instant of image acquisition. The
strobe device to be triggered should have optically isolated inputs. The strobe output
signal is a pulse of 20 to 30 mA, with a duration of about two horizontal line scans. The
polarity of this output is high. The schematic of the strobe output circuit is shown in
Figure 22.
