This gap is due to the warping that is not ideal because it fits to the pixels of the PGU.Dynamic DistortionThe Dynamic Distortion test gives how the virtual image moves when the driver moves into the eyebox.Focus VariationThe Focus Variation corresponds to the average of the sum of the distance between VIEBij and VIEBcentereye.Field CurvatureThe 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.Spot SizeThe Spot Size test gives the diameter of the spot on the virtual image.Pixel SizeThe Pixel Size test gives the angle in minute of arc (arcmin) of the pixel on the virtual image.AstigmatismThe Astigmatism test gives the astigmatism of your system as defined on the picture.ConvergenceThe Convergence test gives the horizontal position difference a point of the virtual image seen by the left eye and the same point seen by the right eye.DipvergenceThe Dipvergence test gives the vertical position difference a point of the virtual image seen by the left eye and the same point seen by the right eye.RotationThe Rotation test gives the angle between the horizontal line of the virtual image and the horizontal line of the target image.Horizontal TrapezoidThe Horizontal Trapezoid test gives the ratio between the size of the left border of the image and the size of the right border of the image.Vertical TrapezoidThe Vertical Trapezoid test gives the ratio between the size of the top border of the image and the size of the bottom border of the image. Horizontal MagnificationThe Horizontal Magnification test gives the ratio between the horizontal size of the virtual image and the horizontal size of the warping.Vertical MagnificationThe Vertical Magnification test gives the ratio between the vertical size of the virtual image and the vertical size of the warping.OverviewThe Overview test gives an overview of all the tests of the OPTIS plugin.Detailed OverviewThe Detailed Overview test gives a detailed overview of all the tests of the Speos plugin. « ReportVirtual Image Distance »
