Using
the View
Image Display
-
This section shows you how to use the View Image display
to help you aim, position, and focus the SLS, and to “fine
tune” the edge location function when the FOV has
unavoidable visual “noise.”
Aiming, Positioning, and Focusing the SLS
You can use the View Image display to aim and position the
SLS for optimum use of the FOV, and focus the SLS.
Figure 6.5 shows an image of the “target” shown in
Figure 6.2 (page 6-3). This is how the image appears
when the SLS is improperly aimed, positioned, and
focused.
Figure 6.5 SLS Improperly Aimed, Positioned, and Focused
The object image is too far to the right in the FOV and too
small (the SLS is not close enough), and the object edges
have considerable slope (the SLS is out of focus).
The SLS is properly aimed when object image is centered
in the FOV. The SLS is properly posifioned when the object
image occupies the largest practicable percentage of the
FOV. The SLS is properly focused when the edges of the
object image are as nearly vertical as possible.
Figure 6.6 shows the same image with the SLS properly
aimed (image is centered), but still improperly positioned
(image is too small) and out of focus.
