Notes:

(1)

Tint: line scanning rate or integration time. Tint is determined by the interval of two start pulses (SP). The module shall be tested at 490us, but it will operate to us

with a clocking speed of 5.0MHz.

(2)

f: main clock frequency. The module was tested at 5.0MHz, but electrically it reliably operates above 5.0MHz.

(3)

Vpavg =

∑ Vp(n)/2432

(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)

(6) Ud = Vdmax – Vdmin

Vdmin is the minimum output on a black document (O.D. = 0.8)

(7)

Vdmax: maximum output voltage on a black document (O.D. = 0.8)

(7) MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]. The DOF range is defined with the MTF. MTF is a measure at the glass surface and at 0.4mm from the

glass > 50 percent and peaks at approximately a 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

Notes:

(1)

Will be tested at 5.0MHz and 490us.

(2)

Will be used as a test for typical value.

(3)

Proposed tint (min.) is the lowest line integration time available at a 5.5MHz clock rate.
