To transform the coordinate system of the nominal topography into the machine coordinate system, it is therefore crucial to know the exact position of the three balls. This becomes possible by determining the zenith positions of each of the three balls using the optical sensor. And of course that that turns around the ray or the wave front, and heads right back to the original position, the origin of the coordinate system. Thus that particular condition is an imaging condition, and we just write our thin lens equation for that imaging condition. And then we'll know how to figure out what focal length is.

The causes of astigmatism is the change in refractive power between the two planes, since a pencil of rays at an angle pass through a different portion of the lens in the meridional and the sagittal planes. On the optical axis, the lens is rotationally symmetric, so the pencil of rays are all in the meridional plane, and astigmatism does not occur. MIT EECS 6.837 Computer Graphics . Ray Tracing .
