Definitions:

1.

Tint is the line scanning rate or integration time. Tint is determined by the interval between two start pulses (SP).

2.

Fclk is the main clock, CP, frequency.

3.

Vpavg =

∑ Vp(n)/1728.

4.

Up = [(Vpmax - Vp) / Vp] x 100% or [(Vp - Vpmin) / Vp] x 100%.

5.

Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%.

Upadj is the non-uniformity percentage pixel-to-pixel.

6.

Ud = Vdmax –Vdmin

Vdmin is the minimum dark output voltage, Vd, with light source off.

Vdmax: maximum dark output voltage, Vd, with light source off.

Vd is measured between the reset level of the video and the dark video signal level. This fixed offset occurs because of the video line is reset to ground after each

pixel and before the following pixel. However, because the video signal is amplified and the offset is adjusted to force the average dark video signal near ground,

the average dark video signal is only few millivolts from ground and reset level will be below ground.

7.

MTF = [(Vpmax - Vpmin) / (Vpmax + Vpmin)] x 100 [%] is the effective algorithm which is used to make the measurements. V(p)max: maximum output voltage at

4.0lp/mm V(p)min: minimum output voltage at 4.0lp/mm.

8.

lp / mm: line pair per mm.
