Definition: (1) Tint: Line scanning rate or integration time. Tint is determ ined by the interval of two SP, start pulses. See note 2 for the high scanning speed op eration. (2) f: main clock frequency. The call out is at 2.0 MHz, but el ectrically it reliably operates to 5.0 MHz. However, it must be optically modified to obtai n the minimum integration time of 167 µ sec. This modification is offered as a user's option. (3) Vpavg = Vp (n)/832 (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 [%]. DOF range is defined with the MTF. MTF is measure at glass surface and at 0.4mm from the glass > 50% and peaks at approximately mid-point of 0.2mm.
