MTF & DOF
1. Tint: line scanning rate or integration time. Tint is determined by the interval of two SP.
2. Fclk: main clock frequency applied to into the module. It is also equal to the pixel frequency.
3. Vpavg = ∑ Vp(n)/832; where Vp(n) is the n^th pixel voltage value
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^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|.
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: 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 glass surface to approximately 0.4mm from the glass surface, and is > 40 percent with its peaks at approximately 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
