8. READOUT MODES
Integration/readout function
The acquisition speed can be set to any value from 0.0001 to 600 fps.
The integration time can also be set. The normal integration time range is [30µs - ~1/fps].
However, integration time of less than 50µs is possible up to 165 ns with degraded performance
(more noise, less dynamic).
Even if sub microsecond integrations are possible, the degradation is higher below ~5µs and depends
on the gain used. Also, below normal minimal integration time, the short integration tuning (cf.9.13.4)
should be used.
Please contact First Light Imaging at support@first-light.fr
for more information regarding very short
exposure time.
Integration time granularity must be set to off to be able to set very small integration times (cf. 9.13.2
Integration time granularity).
Integrate while read (IWR)
For maximum integration time, the camera integrates the signal in IWR mode.
Figure 9:
IWR mode overview.
(1) Variable time: This time (1) is either reset time, or integration time, depending of the FPS and
Tint set by the user.
