Measurement of form of spherical and near-spherical optical surfaces |
| 摘要 |
Rotational motions between a displacement-measuring probe and an optical test surface define a spherical or near spherical datum surface against which measurements of the probe are taken. The probe has a measurement axis that is maintained substantially normal to the optical test surface during the course of measurement.
