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
