9 SPECIAL FEATURES PCO.DICAM C4

9.1.2 DOUBLE IMAGE MODE
How to configure the timing for all channels in double image
mode with
Common Time Properties is explained in this
chapter. This mode is recommended for the pco.dicam C4 for
the most common application scenario where 8 identical
exposure times shall be equidistantly positioned on the time line
corresponding to a constant fps.
Only configure the four parameters accessible under
Common
Time . Do not adjust individual channel settings ( Camera
Timing ), because if you change any value, the Common Time
mode will be deactivated.
You just have to set
Start Delay , Exposure time and Trigger
Related Absolute
/
Relative
. The resulting settings for the four
channels are calculated by pco.camware and displayed under
Camera Timing .
The
Timing Overview shows schematically one time line per
channel with the position of the actual two exposure times
relative to the time lines of the three other channels.
Trigger Related Frame Delay
The offset of the exposure start of the channels, i.e. the delay
between the individual channels in the
Timing Overview is
adjustable in two ways:
Trigger Related Absolute Frame Delay defines the time
difference between the beginning of the exposure time on one
channel and the beginning of the exposure time on the next
channel.
Frame Delay Absolute is displayed in light green as
1xFD, 2xFD, 3xFD for Exposure 1 of each channel and in yellow
for
Exposure 2
of each channel as 4xFD, 5xFD. 6xFD, 7xFD .
Trigger Related Relative Frame Delay
(light green and yellow )
indicates the time interval between the end of the exposure time on
one channel and the start of the exposure time on the next channel.
The following times are the minimum values in Double Image mode:
•
exposure time: 20 ns
•
frame delay absolute: 80 ns
• frame delay relative: 60 ns
•
interframing time between image 1 & 2 (same channel): 300 ns
/ 500 ns
Valid for 20 ns exposure time; the frame delay relative time can be >
or < , if the exposure time is longer.
