Geometry of the Image
a)
Using the PM - 5515 generator, apply the crosshatch pattern with circle.
b)
Adjust the bellow items, until obtaining the best circle symmetry and
positioning, as well as the minor image geometric distortion:
ü
Use the register (
VSl
) to adjust the Vertical slope;
ü
Use the register (
VAm
) to adjust Vertical Height;
ü
Use the register (
VSh
) to adjust Vertical position;
ü
Use the register (
VSc
) to adjust Vertical Center Linearity;
ü
Use the register (
HSh
) to adjust Horizontal position
c)
When done these adjustments, use the registers below to correct another
geometric distortions (see the effect of increasing or decreasing the value
of each register in the images shown within):
