IMAGE SENSOR
CCD area image sensor
S9979
TDI operation / large active area CCD
S9979 is a FFT-CCD area image sensor specifically designed for low-light-level detection in scientific applications. In particular, this image sensor
is ideally suited for extremely low-light-level detection in such fields as spectroscopy and astronomy.
By operating this image sensor in MPP mode, the dark current can be exceedingly reduced. Moreover, use of the low-noise readout amplifier
enables low-light-level detection and long integration time, thus achieving a wide dynamic range.
S9979 has an effective pixel size of 48 × 48 µm and is available in active area of 73.728 (H) × 6.144 (V) mm.

What is TDI operation
In FFT-CCD, TDI operation performs continuous imaging of
a fast-moving object, by transferring the signals at the same
rate as the speed of the moving object. TDI operation allows
acquiring continuous, clear images with high S/N and no
frame breaks.
Since signals of all pixels in each row are accumulated,
sensitivity variations can be drastically improved compared
to two-dimensional operation.
