Mk2 Settings – Projection

When in LaserOS control mode, the Image Setup, Color Balance and Safety Zone settings are handled by LaserOS, so their CubeOS entries remain greyed out.

Test Patterns are still accessible though.

By selecting one of the other control modes, such as Visualizer, the CubeOS stand-alone image settings are made available:

Image Setup

Image power, rotation, X-size, Y-size, X-Flip, Y-Flip, X-Position and Y-Position are configurable. When X and Y size are at 100%, the position sliders have no effect as they cannot move the full-size image beyond the full-size projection area.

The X and Y position sliders have a range of -128 to +128

If the X and Y image size are reduced to 50%, then the X and Y position sliders will move the image with settings between -64 and +64

A good way to get a feel for how the image size affects the amount of positional movement available, is to enable the RGB-THold test pattern (see Test Patterns below) then adjust image size and position in the Image Setup menu.

Color Balance

Color balance settings allow for fine adjustments of maximum and minimum outputs for each color laser, plus the gamma curve for each. The default values should be adequate for most situations, but adjustments are available to allow for precise color matching of multiple projectors.

Safety Zone

The Safety Zone setting, when enabled allows a basic shape to be created for a keep within or keep out zone. The preview toggle (with Laser Interlock Enabled) will project the outline of the safety zone.

By default, it is a keep-within zone and the projected preview color is green.

By setting the invert toggle, it becomes a keep-out zone and the projected preview color is red.

Whilst outside of a keep-within, or inside of a keep-out zone, the laser power is reduced according to the attenuation setting. 100% attenuation means that the out of zone beams are fully blanked. A 90% attenuation would mean that the out of zone beams are reduced to 10% of their normal power.

The Zone shape is selectable between Rectangle, Circle or Ellipse.

The size and position of the zone shape is adjustable using the respective sliders.

The keep-within zone may be useful for defining a target area where the beam may be safely terminated. The keep out zone may be useful for excluding beams from an area when a camera or digital projector is located.

Test Patterns

The built-in test patterns are provided to verify correct operation of the lasers and the scanning system. The RGB Thold pattern is a low brightness one, used for factory setting of the internal laser diode driver. It can also be useful for setting up projectors on site as it has a border that shows the projected image size. Note that this is affected by the rotation, X-size, Y-size, X-Position and Y-Position sliders in Image Setup.
