KAI-2020
1600 (H) x 1200 (V) Interline
CCD Image Sensor
Description
The KAI−2020 Image Sensor is a high-performance 2-million pixel
sensor designed for a wide range of medical, scientific and machine
vision applications. The 7.4 mm square pixels with microlenses
provide high sensitivity and the large full well capacity results in high
dynamic range. The split horizontal register offers a choice of single or
dual output allowing either 18 or 35 frame per second (fps) video rate
for the progressively scanned images. Also included is a fast line
dump for sub−sampling at higher frame rates. The vertical overflow
drain structure provides antiblooming protection and enables
electronic shuttering for precise exposure control. Other features
include low dark current, negligible lag and low smear.

Charge Transfer
Figure 4. Vertical to Horizontal Transfer Architecture
When the V1 and V2 timing inputs are pulsed, charge in
every pixel of the VCCD is shifted one row towards the
HCCD. The last row next to the HCCD is shifted into the
HCCD. When the VCCD is shifted, the timing signals to the
HCCD must be stopped. H1 must be stopped in the high state
and H2 must be stopped in the low state. The HCCD
clocking may begin THD ms after the falling edge of the V1
and V2 pulse.
Charge is transferred from the last vertical CCD phase into
the H1S horizontal CCD phase. Refer to Figure 28 for an
example of timing that accomplishes the vertical to
horizontal transfer of charge.
If the fast line dump is held at the high level (FDH) during
a vertical to horizontal transfer, then the entire line is
removed and not transferred into the horizontal register.
