Notes:
(1) Tint: line scanning rate or integration time. Tint is determined by the interval of two start pulses (SP). The minimum integration time of 500us is available at a
5.2MHz pixel rate but it will require optional light sources.
(2) f: main clock frequency
(3) Vpavg = å Vp(n)/2592
(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 output on a black document (O.D.=0.8).
Vdmax: maximum output voltage of a black document (O.D.= 0.8).
(7) MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]
Vmax: maximum output voltage at 75lp/in
Vmin: minimum output voltage at 75lp/in
(8) O.D. = optical density
(9) lp / in: line pairs per inch
