11-2-4 READOUT TIME OF THE HORIZONTAL LINE
Readout time and exposure time can be varied with Lightsheet Readout Mode for synchronizing the
camera readout with the illumination scan.
Vn = Number of vertical line
1H = 9.744 36 µs to 100 ms
Readout time = Vn × 1H
The range of exposure time with Lightsheet Readout Mode is as shown below.
The maximum exposure time can be decided according to the readout time of a frame, which is longer
than 10 s or not.
1H to (Vn × 1H) : when (Vn × 1H) < 10 s
1H to 10 s
: when (Vn × 1H) ≥ 10 s
