Required metadata for each VAS for audio extraction. A two element vector [horizontaldistance verticaldistance] in millimeters that is the distance from the center of the record to the bottom-left corner of the VAS.
Required metadata for each VAS for audio extraction. A two element vector [width height] in millimeters that is the width and height of the VAS in millimeters.
Vertical Scanning Interferometer
A digital Interferometer that vertically scans through focus. The Fringe Modulation corresponding to each plane of focus is recorded by the detector and transferred to the system's computer. Computerized calculations demodulate the peak Interference signals to determine the Optical Path Difference (OPD), and subsequently, the surface heights.

The short form of the Wyko Vision Software.
Vision ASCII File
An ASCII file defined by Vision that stores the measurement results and parameters in a line by line fashion. See The Wyko Vision ASCII file format. The file extension is .asc.
Vision Automatic Stitching
VAS is a Stitching function that Vision provides, in which the composition of the Stitch Frames from the Batch Measurement is automatically performed after the Batch Measurement is finished. As in VOS, each Single Measurement generates a Dataset as a Vision OPD File, whereas unlike in VOS, these files are automatically deleted when an arbitrary new measurement is made.
Vision OPD File
A binary file that stores the measurement results and parameters in Vision. It is Vision's default Dataset file format. The file extension is .opd.
Vision OPD-file Stitching
VOS is a Stitching function that Vision provides, in which the composition of the Stitch Frames from the Batch Measurement will not be performed after the Batch Measurement is finished. Instead, it will be performed manually through the Vision's Stitching Files function or through a third-party algorithm.
The acronym of Vision OPD-file Stitching.
The acronym of Vertical Scanning Interferometer.

X-Y Sample Stage
The Wyko NT8000 Series Profiler comes with a motorized stage of 8 inches of travel in both the X and Y directions, on which a Sample is placed. The movement of the Stage is controlled in Vision either interactively through mouse via the Intensity Display Window or through Stage File or Stage Grid File.
