The e2v high-resolution focal plane for the instrument was built with an array of five CCD CCD31-40 imaging sensors. The CCD31-40 8192 × 1 pixel device has 12 µm square pixels with readout via two registers, one above and one below the image region. The registers are split in the middle and terminated in four separate output amplifiers. There are also five multispectral bands that cover the spectrum from 450 to 900 nm.
The focal plane design features e2v's new packaging technique, in which the five devices are mounted in close parallel with each other and co-planar to <10 µm.
"e2v is proud to deliver this innovative image sensor focal plane array to SSTL and equip NASRDA of Nigeria with valuable geographically referenced high-resolution imagery,"says Bertrand De Monte, e2v marketing and applications manager.
