NOTES: 12. Light source temperature is 2856
°K. The IR filter used is CM500, 1-mm thick.
13. Saturation is the condition in which further increase in exposure does not lead to further increases in output signal.
14. 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 SRG.
15. Blooming is the condition in which charge induced by light in one element spills over to the neighboring elements.
16. 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 an integration time of 16.66 ms and
a 3.125-MHz vertical-clock transfer frequency.
17. Dark current depends on temperature and approximately doubles every 8 oC. 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.
18. Dark signal is actual device output measured in darkness.
19. Dark signal uniformity is the sigma of the difference between two neighboring pixels taking from all the image area pixels.
20. Dark signal shading is the difference between maximum and minimum of a 5-pixel median taken anywhere in the array.
21. Column uniformity is obtained by summing all the lines in the array, finding the maximum of the difference between two neighboring
columns anywhere in the array, and dividing the result by the number of lines.
22. There will be an estimated 20% degradation in dark current performance when exposed to 320 nm UV light at 1 uWatt/cm2 for
2700 hours.
