b. To add a single point to the table, within the Add Phase section, enter the desired
modulation, in degrees, and click
Add.
The point is added to the table. See Figure 13-6.
Figure 13-6: Add a Single Modulation Phase
Additional points may be added as necessary.
c. To add a phase sweep, within the Add Phase Sweep section, configure the
following parameters:
• Enter the desired modulation Range, in degrees, by specifying the Start Range
and End Range values.
Valid values for the Start/End Ranges are -36000 … +36000.
In addition:
— If Start Range < End Range, the sweep proceeds in a positive/
counterclockwise direction.
— If End Range < Start Range, the sweep proceeds in a negative/clockwise
direction.
• Enter the desired Increment, in degrees, between successive points along the
sweep.
An appropriate Increment value must be chosen such that when stepping from
the Start Range through to the End Range, the result is a whole number of steps.
NOTE:
LightField automatically calculates, and displays, the number
of points to be added based on the
Range and Increment
values used. If the result is not a whole number of steps, an
error message is displayed.
Although Start/End Range values up to ±36000° (inclusive) are valid, the specified
range will be converted/shifted to a standard [0 … 359] degree scale, and the
corresponding number of points will be added to LightField. Once any sweep in
excess of 359° reaches the 360° mark, it “returns” to zero and continues sweeping
through the next 359°. The sweep continues in this manner until it has swept
through the entire range.
