Appendix A: Frequently Asked Questions
Q:
A:
The green lines are the analog signal on the photodiode, which
decrease as a result of exposure. The slope is determined by the
amount of light at each pixel (the more light the steeper the
slope). When the pixels reach the saturation level the analog
signal does not change despite further exposure. As shown,
without any double slope pulse pixels p3 and p4 reaches
saturation before the sample moment of the analog values; no
signal is acquired without double slope. When double slope is
enabled a second reset pulse is given (blue line) at a certain time
before the end of the integration time. This double slope reset
pulse resets the analog signal of the pixels below this level to the

reset level. After the reset the analog signal starts to decrease
with the same slope as before the double slope reset pulse. If the
double slope reset pulse is placed at the end of the integration
time (90% for instance) the analog signal that reach the
saturation levels are not saturated anymore (this increases the
optical dynamic range) at read out. It is important to note that
pixel signals above the double slope reset level are not influ-
enced by this double slope reset pulse (p1 and p2). If desired,
additional reset pulses can be given at lower levels to achieve
multiple slope.
