spurious nonuniformity specification

The spurious nonuniformity specification of the TC281 CCD grades – 30 and – 40 is based on several

performance characteristics:

–

Black

–

White

The CCD sensors are characterized in both an illuminated condition and a dark condition. In the dark condition,

the nonuniformity is specified in terms of absolute amplitude as shown in Figure 6. In the illuminated condition,

the nonuniformity is specified as a percentage of the total amplitude as shown in Figure 7.
