Tint: line scanning rate or integration time. Tint is determined by the interval of two start pulses (SP).
Fclk: main clock frequency applied to into the module. It is also equal to the pixel frequency.
Vpavg =
∑
Vp(n)/832; where Vp(n) is the n
th
pixel voltage value
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
th
video pixel, Vp(n), and Vpmin is determined by minimum pixel, Vp(n), then Up is selected from the largest of the two values |Upmax| or |Upmin|.
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
Vdmin is the minimum output in the dark
Vdmax is the maximum output voltage in the light
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
lp / inch: line pair per inch
