Summary
| Description | thumb|right|400px|Illuminations for different orientations. Left: the blue and orange positions in the pupil (poles) are both satisfactory for imaging the horizontal pitch. Right: the orange position can image the diagonal pitch but with poor depth of focus, but the blue cannot produce the image when light is scattered beyond the numerical aperture (black circle). Different orientation pitches will require different illuminations.refW. N. Partlo et al., Proc. SPIE 1927, 137 (1993).</ref> The colored patterns on the right are matched to the corresponding pupil locations on the left. |
