Another Hint: A good time to use Z Axis Scaling is when you need to view the low energy down in the wings of
your laser beam. Kick the scaling up to x8, leave the scale scroll bar at the bottom of the slider, and maybe add in a
little video gain and some frame averaging to quiet the noise. You’ll be amazed at what you can see!
3.2.7.7 Beam Display
You can change how your beam is displayed without actually changing how it is processed nor
how it is stored in the frame buffer. With these choices you can visually compare your Current
selected Beam Display to a beam profile stored in the Reference frame buffer. Or compare it
to your beam with the reference added or subtracted from it. Or just display your current beam
added to or subtracted by the reference beam.
The choices here seem obvious, however the impact on your display may be a bit disconcerting
when first viewed, so some explanation is in order.
First, the definition of Current means the frame buffer location indicated in the frame counter at
the bottom of the main display window. In other words, the frame you currently have decided to
view. If you are running, then the current frame will be cycling.
The Reference frame is whatever you last saved into the reference frame buffer, location 0
(zero).
For 99% of the majority of users the Beam Display will be set to Current Alone, and rarely be
changed.
For those other 1%, and you know who you are, read on...
3.2.7.7.1 Current and Reference:
2D You must have both Cursors and Cursor Profiles enabled for this feature to operate.
The Current beam alone will appear in the display. A second profile, drawn in Lt. Gray will
also appear in the display. This profile is a projection of the Reference beam. All projections
are made from the Cursor positions.
3D The Current beam will be displayed in Red. The Reference will be displayed in Blue. If
cursors are enabled they will follow the contour of the Current beam.
3.2.7.7.2 Current and Current - Reference:
2D You must have both Cursors and Cursor Profiles enabled for this feature to operate.
The Current beam alone will appear in the display. A second profile, drawn in Lt. Gray will
appear in the display. This profile is a projection of the Current beam minus the Reference
beam. All projections are made from the Cursor positions.
3D The Current beam will be displayed in Red. The Current minus the Reference will be
displayed in Blue. If cursors are enabled, they will follow the contour of the Current beam.
3.2.7.7.3 Current and Current + Reference:
2D You must have both Cursors and Cursor Profiles enabled for this feature to operate.
The Current beam alone will appear in the display. A second profile, drawn in Lt. Gray will
