Light source temperature is 2856 °K. The IR filter used is CM500 1mm thick. Integration time is 1/30 sec. 8. This is a signal pedestal measured from the output level after reset to the output level after the SRG negative transition without any light input into the sensor. 9. Blooming is the condition in which charge induced by light in one element spills over to the neighboring elements. 10. 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 33.33 ms and 8 MHz vertical clock transfer frequency. 11. Dark current depends on temperature and approximately doubles every 8 °C. 12. Dark signal is actual device output measured in dark. 13. Dark signal uniformity is the sigma of difference of two neighboring pixels taken from all the image area pixels. 14. Dark signal shading is the difference between maximum and minimum of 5 pixel median taken anywhere in the array. 15. Spurious non-uniformity is the signal of no more than three neighboring pixels that exceeds or is less than average. 16. 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. pixel defect specifications, integration time = 1/60 sec, temperature = 40 °C DEVICE PART NUMBER DEVICE IN DARK DEVICE ILLUMINATED TOTAL DEFECT COUNT DEFECT COUNT NUMBER WS BS WS/BS DEFECT COUNT NUMBER WS SIGNAL OUTPUT LEVEL AREA AREA AREA AREA A B A B A B A B TC341-20 > 3.5 mV 0 0 0 0 0 0 > 5% 0 0 50 mV +/– 10 mV 0 TC341-30 2.5~3.5 mV 2 5 2 5 2 2 5~7.5% 2 5 12 > 3.5 mV 0 0 0 0 0 0 > 7.5% 0 0 TC341-40 3.5~7 mV 3 7 3 7 3 7 7.5~15% 3 7 15 > 7 mV 0 0 0 0 0 0 > 15% 0 0 17.
