During normal operation, the impinging photons in or near the PN photodiode junction
generate free charges that are collected and stored on the junction's depletion capacitance.
Since on average a certain fraction of charge is generated and collected for each impinging
photon, the number of collected charges will proportionally increase with light exposures.
Figure 3 shows the stored signal charge as function of light exposure at a wavelength of
575 nm. The exposure is the product of the light intensity in nW/cm
2
and integration time in
seconds. The charge accumulates linearly until reaching the saturation charge where the
corresponding exposure is the saturation exposure.
