Definition:
(1) Tint: Line scanning rate or integration time. Tint is determined by the interval of two
SP, start pulses.
(2) f: main clock frequency,
(3) Vpavg = ∑ Vp(n)/1248
(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 nonuniformity percentage pixel to pixel
(6) 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)
(7) MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]
Vmax: maximum output voltage at 5.9 lp/mm (At the optical Nyquest Frequency)
Vmin: minimum output voltage at 5.9 lp/mm
(8) O.D. = Optical Density
(9) lp / mm: line pair per mm
Recommended Operating Conditions (25 °C)
