Description
1997A–IMAGE–05/02
TH7834C high resolution linear array consists of 12000 useful pixel photosensitive line,
associated with four CCD shift registers and four output amplifiers. Transfer gates on
both sides of the photosensitive line enable delivery of charges, respectively:
• on one side, charge accumulated by odd pixels (1, 3, 5… 11999), to CCD shift
registers A and C,
• on the other side, charge accumulated by even pixels (2, 4, 6… 12000), to CCD
shift registers B and D.
Shift registers 1 and 2 collect charges generated by one half of the photosensitive line
(pixel 1 to 6000), whereas shift registers 3 and 4 collect charges generated by the sec-
ond half of the photosensitive line (pixels 12000 to 6001).
