which gives large deviation in optical measurement is observed in Q2, pair 0:
pair: S1 S2 dS1 dS2 L1 L2 dL1 dL2 <dS/L> angle(deg) D1 D2 dD d(dS) d(dL) Quad 2 pair: 0 20915 20685 31 -199 43544 43309 -17 -252 -0.00194 -0.11124 47993 48308 -315 230 235
Responsible for this effect is Q2, point 7:
Quad 2 Sensor X Y Z 7 43298 44099 -2
Add 200 to both, X and Y and changed to:
7 43498 44299 -2
Corrected file 2013-04-19-Run7-DS1-Metrology-corr.txt gives a consistent table for QC and is used for alignment.
QC procedure and results
We calculate
S1 - 1st short side length of 2x1
S2 - 2nd short side length of 2x1
L1 - 1st long side length of 2x1
L2 - 2nd long side length of 2x1
D1 - 1st diagonal of 2x1 between corners 1 and 3
D2 - 2nd diagonal of 2x1 between corners 2 and 4
dS and dL are the deviations of the 1st and 2nd corner along the short and long sides, respectively. The sign of all dS are chosen in order to provide correct sign for the tilt angle (the same direction for all 2x1 sensors).
<dS/L> - the tilt angle of 2x1 averaged over two sides in radians.
angle(deg) - the same angle in degrees.
dD = D1 - D2
d(dS) = dS1 - dS2
d(dL) = dL1 - dL2
Quality check parameters for the perfect measurement:
- S1=S2, L1=L2 - the 2x1 sides should have equal length and width,
- D1=D2 - the 2x1 diagonals should be equal,
- dS1 = dS2 = 2*dL1 =2*dL2 - tilt angle should provide consistent deviation for all corners,
- dD=0, d(dS)=0, and d(dL)=0 - within precision of measurement.
Everything, excluding <dS/L> and angle(deg), are in micrometers.
