- W1978045998 abstract "Tilt and offset of aspheric surfaces are detected by a narrow aperture interferometer which performs a zonal rotary scan by means of a precise air-bearing spindle. Positioning of unknown aspheric surfaces with respect to machining or measuring apparatus requires centration of the samples (i.e. tilt and offset) and also longitudinal setting. The accuracy of the scanning interferometer is based on the precise axis of rotation of an Intop-Watt-type air-bearing spindle which steers the contactlessly probing laser interferometer beam on a conical path. Thus, a center and an axis of symmetry are defined. The system allows alignment of the aspheric surface and it also permits to detect coincidence between the scan-cone apex and the center of the sphere best fit to the zone being scanned.© (1981) COPYRIGHT SPIE--The International Society for Optical Engineering.
