spurious nonuniformity specification
The spurious nonuniformity specification of the TC217 CCD grades â30 and â40 is based on several sensor
characteristics:
⢠Amplitude of the nonuniform line or pixel
⢠Polarity of the nonuniform pixel
â Black
â White
⢠Column amplitude
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 14. In the illuminated condition,
the nonuniformity is specified as a percentage of the total illumination as shown in Figure 15.
The nonuniformity specification for the TC217 is as follows (CCD video-output signal is 50 mV ±10 mV):
