Notes: 9. Light source temperature is 2856 °K. The IR filter used is CM500 1mm thick.
10. Saturation is the condition in which further increase in exposure does not lead to further
increases in output signal.
11. Zero input offset is the residual output signal measured from the reset level with no input
charge present. This level is not caused by the dark current and remains approximately
constant independent of temperature. It may vary with the amplitude of SRG1.
12. Blooming is the condition in which charge induced by light in one element spills over to the
neighboring elements.
13. Smear is the measure of error signal introduced into the pixels by transferring them through
the illuminated region into the memory. The illuminated region is 1/10 of the image area
height. The value in the table is obtained for the integration time of 16.66ms and 1.0 MHz
vertical clock transfer frequency.
14. Dark current depends on temperature and approximately doubles every 8 C^o. Dark current
is also multiplied by CCM operation. The value given in the table is with the multiplier
turned off and it is a calculated value.
15. Dark signal is actual device output measured in dark.
16. Dark signal uniformity is the sigma of difference of two neighboring pixels taking from all
the image area pixels.
17. Dark signal shading is the difference between maximum and minimum of 5 pixel median
taken anywhere in the array.
18. Column uniformity is obtain by summing all the lines in the array, finding the maximum of
the difference of two neighboring columns anywhere in the array, and dividing the result by
number of lines.
