Flicker Mode
: The Flicker Mode can be changed in the Flicker Mode Panel
④
. You
can choose between square, sine, and triangle waveshape.
•
Phaseshift
: To change the Phaseshift of the module, you can enter the Angle and
Period Count
⑥
. The Period Count is the number of periods the module goes through
before it adds the Phaseshift with the angle defined. Note that the Phaseshift will be
turned off if the intensity is changed.
•
Intensity Interval
: The Intensity Interval under
⑤
sets the range of the Intensity slider
in percent. The intensity is divided into decades to match the human perception better.
•
Flicker Controls
: Change the intensity, the flicker frequency, or the duty cycle value
with the sliders or enter the desired values into the edit field
⑦
. When an edit field is
selected, you can use the
“up” and “down” arrows on the keyboard to change the value.
If “Flicker” is set to 0.0Hz, the module lights continuously, and the “Duty Cycle” slider is
inactive.
If the selected module is calibrated and in continuous mode, the current luminance/illuminance
values are shown in the source panel
⑧
. It also shows the temperature of the modules.
The preview panel
⑨
provides a graphical representation of the current Intensity, Flicker, and
Phaseshift settings. The width of the preview represents one second.
All connected Vega modules are stored for the current session and will be restored the next
time the software is executed.
4.3.2 Presets
Add presets of all connected modules
by clicking the „Add Preset“ button. The added presets
show up in the
“Presets” list
②
. Clicking on the presets will immediately switch to it. Rename or
delete presets via the context menu. Alternatively,
press “F2” to rename or press the “del”
button to delete a preset.

4.3.3 Calibration
The Vega has a stabilized intensity output. The system needs to be calibrated to use the output
feedback in cd/m² or lux. The Vega provides two calibration modes.
•
Luminance calibration
: Luminance is a measurement of the emission or reflection from a flat
surface in cd/m². For Vega, the chart surface is measured. The diffuser plate, however, is
