Tint: Line scanning rate or integration time. Tint is determined by the interval of two SP.
f: main clock frequency
Vpavg =
∑
Vp(n)/1248
Up = [(Vpmax - Vp) / Vp] x 100% or [(Vp - Vpmin) / Vp] x 100%
Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%
Upadj is the non-uniformity percentage pixel to pixel
Ud = Vdmax – Vdmin
Vdmin is the minimum output on a black document (O.D.=0.8)
Vdmax: maximum output voltage of black document (O.D.= 0.8)
MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]
Vmax: maximum output voltage at 75lp/in
Vmin: minimum output voltage at 75lp/in
O.D. = optical density
lp / in: line pair per inch
