3.2.7.5Beam Colors

Your choice of beam display colors depends upon which display mode you have selected. There are 3 choices available in both 2D and 3D modes, plus 2 additional choices in 3D mode. They are:

Color Bands: 16 colors plus white to indicate intensities at, or near, A/D converter saturation. Available in both 2D and 3D.

Color Continuous: 128 colors plus white to indicate intensities at, or near, A/D converter saturation. Available in both 2D and 3D.

Gray Scale: 128 shades of gray plus red to indicate intensities at, or near, A/D converter saturation. Available in both 2D and 3D.

Green: Available only in 3D mode, a monochrome shade of green that can be used with laser goggles that do not filter the green wavelengths. White is used to indicate intensities at, or near, A/D converter saturation.

Yellow: Available only in 3D mode, a monochrome shade of yellow that can be used with laser goggles that do not filter the yellow wavelengths. White is used to indicate intensities at, or near, A/D converter saturation.

Note: In the above selections, data that is representing negative energy values will be displayed in dark gray, except in the case of the gray scale, dark blue.

User Palette: This selection allows the user to select a color palette that they have

custom designed. When selected a Palette button will appear in the Display Toolbar. When you click on this button you will be allowed to select one of your custom palette files for both 2D and 3D displays. See section 3.2.10 about how to create a custom palette.

These basic color schemes can be augmented by some other display choices. In particular, choosing Z Axis Scaling greater than x1, enabling 3D Contour displays, and Beam Display selections that involve more than one beam at a time will modify how your beam will be displayed.

3.2.7.6Z Axis Scale

You can expand the intensity or Z Axis Scale in both 2D and 3D display modes. An expanded Z axis will allow you to view a narrower range of intensities in more detail. The Z axis scaling will yield slightly different imaging results depending upon which Beam Colors you have selected. To activate Z Axis Scaling, select a magnification factor greater than x1. A good value to practice when using this feature is a conservative x2. When Z axis scaling is activated, a vertical scroll bar will appear along the right edge of the beam display window. You can use this scroll bar to slide the expanded viewing range up or down the full Z axis scale.

In 3D mode, it is easy to see where the expanded display region boundaries end and the outside region begins. To assist you in the 2D display mode, a pair of dashed lines will indicate the magnified range in the Cursor Profiles. Of course, to see these indicators you must have the Cursor Profiles turned on and the Cursors passing through the beam profile.

Hint: Use Z Axis Scaling with: Beam Color set to Color Continuous, 2D Cursor Profiles turned on, and Cursors set to Centroid.
