The sensor resolution and the readout time (t
readout
) can be found in the respective
Technical Data Sheet (TDS). For the example a full frame resolution is used.
▪
The exposure time (t
exposure
) is manually set to
6
msec.
▪
The resulting data volume is calculated as follows:
Resulting Data Volume = horizontal Pixels × vertical Pixels × Pixel Depth
All the cameras are triggered simultaniously.
The transmission delay is realized as a counter, that is started immediately after the sen-
sor readout is started.

In general, the transmission delay is calculated as:
Timings:
A - exposure start for all
cameras
B - all cameras ready for
transmission
C - transmission start
camera 2
D - transmission start
