The ES-8k-68 kHz is a member of the Piranha
ES family - DALSA's latest generation of high sensitivity,
Time Domain Integration cameras.
Incredible sensitivity. Incredible speed.
TDI is a method of line scanning which provides dramatically increased
responsivity compared to other video scanning methods and is based
on the concept of accumulating multiple exposures of the same (moving)
object, effectively increasing the integration time available to collect
incident light. The TDI linescan sensor is made up of multiple lines of
pixels. As an object passes under each line it is imaged and added to
the image taken under the previous line.
These cameras are capable of bidirectionality with up to 32 stages of selectability, while preventing over-exposure with DALSA's proven 100x antiblooming.
If you need cost effective
maximum performance in low light, consider a Piranha ES.
