Definition:
1. Tint is an integration time. It is determined by the internal of two start pulses.
2. λ is a wavelength of the light source.
3. Ta is ambient temperature.
4. Vp = (Vpmax + Vpmin) / 2
where Vpmax is a maximum voltage of whole module on white document.
Vpmin is a minimum voltage of whole module on white document.
5. Up is a pixel - pixel photo response non-uniformity within whole module.
Up = [(Vpmax - Vpmin) / Vp] x 100%
6. Upadj = Max [|(Vp(i) - Vp(i+1)| / Vp(i)] x 100%
where Vp(i) is the video signal output of each pixel # i
Vp(i+1) is the video signal output of each pixel # (i+1)
7. Vd = (Vdmax + Vdmin) / 2
where Vdmax is a maximum dark signal on whole module.
Vdmin is a minimum dark voltage on whole module.
8. Ud = Vdmax - Vdmin
9. MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100%
where Vmax is the maximum output voltage at 3.85 lp/mm document.
Vmin is the minimum output voltage at 3.85 lp/mm document.
10. γ = log[(V2-Vd) / (V1-Vd)] / log (E2/E1) or log [(V2 - Vd) / (V1 - Vd)] / log (T2/T1)
where V1 is the output voltage of E1 illumination or T1 integration time
V2 is the output voltage of E2 illumination or T2 integration time
at 10 ~ 90% of saturation conduction.
11. O.D. = optical density of the paper.
12. lp / mm = line pair per millimeter
