Definition of PRNU : PRNU = a x 100 (%) Where 7 is average of total signal outputs and Ax is maximum deviation from % under uniform illumination. (Channel 1) In the case of 3750 elements (Channel 2), the condition is the same as above too. (Note 3) VsatT is defined as minimum saturation output voltage of all effective pixels.

DSNU is defined as different voltage between VprK and VimpK when Vypk is maximum dark signal voltage. os VDRK DsNU Vi (Note 6) Definition of DR: DR= SAT. VDRK VprK is proportional to tjyT (Integration Time). So the shorter tjyT condition makes wider DR values.

- Window Glass The dust and stain on the glass window of the package degrade optical performance of CCD sensor. Keep the glass window clean by saturating a cotton swab in alcohol and lightly wiping the surface, and allow the glass to dry by blowing with filtered dry N2. Care should be taken to avoid mechanical or thermal shock because the glass window is easily to damage. 2. Electrostatic Breakdown Store in shorting clip or in conductive foam to avoid electrostatic breakdown. 3. Incident Light CCD sensor is sensitive to infrared light. Note that infrared light component degrades resolution and PRNU of CCD sensor. 1997-06-30 10/11
