Field Curvature
The Field Curvature test gives the distance between the virtual image and a plane normal to the optical axis at the center of the virtual image.

In detail:
For each sample VIij of the virtual image, the "Field Curvature" gives the mean of the Field Curvature for VIij over the EBij samples of the binocular eyebox, expressed in millimeter.
Field Curvature for VIij: For each sample EBij of the binocular eyebox, the field curvature for VIij is the distance from the sample VIij of the virtual image seen from the sample EBij of the binocular eyebox to the normal projection of this sample on the plane normal to the optical axis at the center of the virtual image seen from the sample EBij of the binocular eyebox.
Optical axis: For each sample EBij of the binocular eyebox, the optical axis is the line between the sample EBij of the binocular eyebox and the center of the virtual image seen from the sample EBij of the binocular eyebox.
The result of the computation is displayed as a table that contains the "Field Curvature" computed for each sample VIij of the virtual image.

There is one table result by configuration created.
Each table has the size of the sampling of the virtual image.
The test also displays a sum up, for each configuration, of the Average, the Standard deviation, the Minimum and the Maximum of the value contained in the table.
