Figure 15. Double Slope Response
Non-destructive Read Out (NDR)
The default mode of operation of the sensor is with FPN
correction (double sampling). However, the sensor can also be
read out in a non-destructive way. After a pixel is initially reset,
it can be read multiple times, without resetting. The initial reset
level and all intermediate signals can be recorded. High light
levels will saturate the pixels quickly, but a useful signal is
obtained from the early samples. For low light levels, one has
to use the later or latest samples. Essentially an active pixel
array is read multiple times, and reset only once. The external
system intelligence takes care of the interpretation of the data.
Table 14. summarizes the advantages and disadvantages of
non-destructive readout.

Advantages
Disadvantages
Low noise - as it is true CDS. In the order of 10 e- or below.
System memory required to record the reset level and the
intermediate samples.
Requires multiples readings of each pixel, thus higher data
throughput.
Requires system level digital calculations.
High sensitivity - as the conversion capacitance is kept rather
low.
High dynamic range - as the results includes signal for short
and long integrations times.
