Structure of a CCD 1.
The image area of the CCD is positioned at the focal
plane of the telescope. An image then
builds up that
consists of a pattern of electric charge. At the end of
the exposure this pattern is then transferred, pixel at a
time, by way of the serial register to the on-chip
amplifier. Electrical connections are made to the outside
world via a series of bond pads and thin gold wires
positioned around the chip periphery.
