Density Defects
STEP 1: Drawing Measurement Regions
CHECK
CHECK
Draw a figure in the section to be inspected.
Do not include areas with marks and patterns in the measurement region. It
will not be possible to distinguish them from surface detects, and measure-
ment will not be performed properly.
Position detection can be also performed using algorithms for detecting
defects.
When a measurement region is drawn, measurement is performed for the dis-
played image and the results are registered as the reference values (X and Y
coordinates of the position where the defect was found). This position
becomes the reference position, so be sure to place the measurement object
in the correct position before drawing the measurement region.
