Copy Image to Wallpaper
When this button is clicked, the currently displayed frame image will be copied to
the Desktop Wallpaper. This tool has no real practical application except to
provide bored operators with something meaningless to do. Besides, why not
proudly display your colorful beam profiles for the entire world to see?
2D Only Beam Display Properties
Note: The following Beam Display dialog box items only affect the 2D beam display.
 Cursor Profiles - Check this item to have Cursor Profiles appear along the
bottom and left edges of the beam display. The profiles will display a projection
of the beam intensity through the pixels where the Cursors are drawn. If
Cursors are turned off, no profiles will be displayed.
• If the beam display is in color, the profiles will be drawn in white.
• If the beam display is in shades of gray, the profiles will be drawn in red.
• Cursor Profile displays do not plot negative values below the noise floor.
 Crosshair – Add a crosshair mark to the 2D display. Use the location of the
Crosshair to make a straight-line distance measurement from the crosshair to the
intersection of the cursors. The distance from the crosshair to the cursor is
shown on the lower status bar as the Delta display:
Although the crosshair is not visible in a 3D display, the Delta distances are still
valid, based on how they were last set.
• Off – No Crosshair will be displayed.
• Manual – The operator manually determines the crosshair location.
• Centroid – The crosshair location is automatically drawn at the
computed centroid of the beam. Note: This operation will not function
correctly if the results window is minimized.
• Peak – The crosshair location is automatically drawn at the peak energy
location of the beam. Note: This operation will not function correctly if
the results window is minimized.
• Origin – The crosshair location indicates the position of the origin. Note:
The crosshair might not be displayed if the origin location is outside the
display window, or it might be in an upper or lower left corner.
To manually position the crosshair, use the mouse to drag and drop it. Move the
mouse pointer to the intersection point of the crosshair. When the pointer changes
to the crosshair drag
symbol press and hold down the left mouse button and
drag the crosshair to a new location. Release the mouse button to position the
crosshair.
The crosshair can also be used to position the Manual Origin Location. If the
Origin is set to Manual mode, and the Crosshair set to Origin, when the
crosshair is moved, the origin moves with it.
Note: It is possible for the Crosshair/Origin to be located outside of the current
viewing area of the Display and thus, not visible. Check the Pan/Zoom
window’s red dot to locate the origin.
