Ti

2.

F

nt: line scanning rate or integration time. Tint is determined by the interval of two SP.

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

g] x 100%; where Upmax is determined by the highest

m the largest of the two values |Upmax| or |Upmin|.

100 [%]. Depth of focus, DOF, range is defined with the MTF

0.4mm from the glass surface, and is > 40 percent with its peaks at approximately mid-point, 0.2mm.

3.

Vpavg =

∑ Vp(n)/832; where Vp(n) is the n pixel voltage value

4.

Up is defined as follows: Upmax= [(Vpmax - Vpavg) / Vpavg] x 100% and Upmin= [(Vpavg - Vpmin) / Vpav

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%

Ud = Vdmax – Vdmin

6.

Vdmin is the minimum output in the dark.

Vdmax: maximum output voltage in the light.

7.

MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x

MTF is measured at glass surface to approximately

Vmax: maximum output voltage at 50lp/inch (At 1/2 of the optical Nyquest frequency)

Vmin: minimum output voltage at 50lp/inch

lp / inch: line pair per inch
