How to Measure Streaking Value
Driving timing:
1. The electron in V-cell is cleared by 750 lines (1.5 times normal operation) vertical transferring from V-cell to
storage area.
2. The electron in PD-cell is moved to V-cell.
3. The electron in 250 V-cell is moved to storage area by 250 parallel pulses (0.5 times as normal operation).
4. The electron in the last line of storage area is moved to serial resister.
5. The electron in serial resister is moved out by 2046 serial pulses (3 times as normal operation).
6. All the electrons in storage area are moved out by repeated 500 times both (4) and (5). Then the following
image is out.
Measurement condition:
CMG: 1000 times
Thermistor temperature: -15°C
Light intensity: 10 Lx
Calculation:
The value of streaking is difference between the average of the electron in streaking area and the one in
area B.
