AW00118302000 Acquisition Control
Basler racer GigE 115
The line start trigger goes low to end the exposure for line acquisition N+1 before readout for
acquisition N has ended (premature exposure end; see Fig. 40 on page 116).
This would result in the illegal overlap of two readouts (in trigger width exposure mode only).
Fig. 39: Exposure N+1 Illegally Starts Before the Exposure Overhead for the Preceding Line Acquisition N Has
Ended; the Shown Overlap of Readouts is Also Illegal; Timed Exposure Mode Used as an Example
The exposure overhead (see Fig. 39 on page 115) is part of every exposure
process. For simplicity, it is omitted from the other figures illustrating exposure
and readout (see, for example, Fig. 40 on page 116).
The duration of the exposure overhead is expressed by constant C
1
(see also
Section 8.5 on page 135).
