Temperature dependence of dark signal
The above graph is measured on an IBIS4-1300 under
nominal operation, using breadboard. This particular sensor
has about 100 "bad pixels" at RT.
Average offset (=dark signal) and RMS (=FPN of dark signal)
are measured versus temperature. Offset is referred to the
"short tint" offset at 20 C. Integration time was 160 ms (= "long
tint").
Y-axis is the output signal (100% = ADC range)
Useful range of "double slope"
Which total dynamic range can reasonably be obtained with
the dual slope feature of the IBIS4-1300?
Assuming that the "regular" S/N is 2000:1, and that one can
put the knee point halfway the voltage range, the each
piecewise linear halve has 1000:1 S/N. If the ratio between
slopes is a, then the total dynamic range becomes
(1000+a*1000):1.
Example, is a=10, then the total dynamic range becomes
11000:1.
