Full Frame CCD Image Sensor FTF3020-C
Architecture of the FTF3020-C
The optical centres of all pixels in the image section form a square
grid. The charge is generated and integrated in this section. Output
registers are located below and above the image section for read-
out. After the integration time, the image charge is shifted one line
at the time to either the upper or lower register or to both
simultaneously, depending on the read-out mode. The left and the
right half of each register can be controlled independently. This
enables either single or multiple read-out. During vertical transport,
the C3 gates separate the pixels in the register. The central C3 gates
of the lower and upper registers are part of the left half of the sensor
(W and Z quadrants respectively). Each register can be used for
vertical binning. Each register contains a summing gate at both ends
that can be used for horizontal binning (see figure 2).
