1. Tint: line scanning rate or integration time; tint is determined by the interval of two SP. See Note 2 for the high scanning speed operation.
2. f: main clock frequency; the call out is at 2.0MHz, but electrically it reliably operates to 5.0MHz. However, it must be optically modified to obtain the minimum
integration time of 167µsec. 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 percent and peaks at approximately mid-point of 0.2mm.
Vmax: maximum output voltage at 50lp/inch (At 1/2 of the optical Nyquest Frequency). Vmin: minimum output voltage at 50lp/inch.
8. O.D. = optical density
9. lp / inch: line pair per inch

* Tint (min.) is the lowest line integration time available at a 5.0MHz clock rate with internal optical modifications. See Note 2 under Table 4.
