Notes:

(1)

Tint: line scanning rate or integration time. Tint is determined by the interval of two start pulses (SP).

(2)

Fclk: main clock frequency applied to into the module. It is also equal to the pixel frequency.

(3)

Vpavg =

(4)

Up is defined as follows: Upmax= [(Vpmax - Vpavg) / Vpavg] x 100% and Upmin= [(Vpavg - Vpmin) / Vpavg] x 100%; where Upmax is determined by the highest

n

(5)

Upadj is between two adjacent pixel's non-uniformity and defined as follows:

Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%

(6)

Ud = Vdmax – Vdmin

Vdmin is the minimum output in the dark

Vdmax is the maximum output voltage in the light

(7)

MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]. Depth of focus ( DOF), range is defined with the MTF. MTF is measured at the glass surface to approximately

0.4mm from the glass surface, and is > 40% with its peaks at approximately the mid-point, 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)

lp / inch: line pair per inch
