Binning Modes, D-TDI lines and Scanning Speed
The tables below shows the predicted maximum scanning speeds for both Shad-o-
Scan 3001 and 4501 detectors vs. binning modes and number of Digital TDI lines at
maximum framerate.

Frame Concatenation
The Frame Concatenation functionality offers the possibility of concatenating (i.e.
stitching) a number of frames into a single frame.
In case of small number of Digital TDI lines combined with high frame rates, the GigE
Vision frame overhead (leader/trailer packets) increases the ethernet bandwidth
usage which prevents the image acquisition from correctly operating at the maximum
frame rate. For this, a solution is found in concatenating a programmable number of
frame
s into a ‘super frame’ in the detector
. This super frame is sent to the host with
only one set of GigE overhead. On the host computer, the final reconstruction and, if
applicable, Digital TDI can be executed.
The
FrameCatenateNofFrames
feature (with display name
Number of Frames to
Concatenate
)
can be found under the
Image Format Controls
group:
