NOTES:

9. Sensitivity is measured at an integration time of 33 ms with a source temperature of 2859 K. A CM-500 filter is used. Sensitivity is

measured at any illumination level that gives an output voltage level less than VU.

10. VU is the output voltage that represents the threshold of operation of antiblooming. VU ≈ 1/2 saturation signal.

11. Saturation is the condition in which further increase in exposure does not lead to further increase in output signal.

12. Blooming is the condition in which charge is induced in an element by light incident on another element. Blooming overload ratio

is the ratio of blooming exposure to saturation exposure.

13. Dark-signal level is measured from the dark dummy pixels.
