Trillium User’s Manual 69 TRILLIUM USER'S MANUAL Appendix E: Dark Offset De-rating Curve D1. Overview At high temperatures and low line rates, the increase in CCE by the IL-P3 sensor results in large dark offsets, caused by the amplification of temperature generated dark signal integrated over long periods. This effect has an impact on the ability of the Trillium camera to correctly calibrate itself. The plots below detail the offset characteristics and associated limits for successful calibration. The first plot shows the limit for cc3 being able to calibrate the camera (without a dark reference) and meet the calibration accuracy specifications: Blue Channel I nt egration Time Pl ots of O ffset vs Temper ature DN Offset 20 15 10 5 0 0 10 20 30 40 50 Te mp.
