Description
These controls allow the user to (a) specify whether polarization information should be tracked at all during the raytrace, and (b) specify the starting polarization states of the rays as generated by the source. Note that unless the Polarized option is toggled, polarization data is not tracked at all during the raytrace.
Navigation
This feature can be accessed by selecting the Polarization tab in a Detailed Source dialog box.

Polarized / No Polarization Defined
|
If the Polarized option is selected, then polarization state information of the rays is maintained and stored for each ray.
|
No Polarization Defined

Polarization Properties
|
|
Ellipticity
|
Sets Ellipticity of the polarization state. Linear and circular can be selected directly or an arbitrary ellipticity (0<e<1) may be entered. There is also the option to randomize the ellipticity.
|
Linear
|
|
Handedness
|
Sets the handedness of the polarization state. Options are right handed, left handed, or randomly chosen handedness. If the ray is propagating towards you, the electric field vector rotates in a clockwise direction for Right handedness and counter-clockwise for Left handedness.
|
Right Hand
|
|
Angle of Polarization Ellipse
|
|
Angle of major axis
|
The angle of the polarization ellipse relative to the local X axis.
|
Exact 90
|
|
X, Y, Z
|
The direction cosine vector of the local X axis used for the angle of the polarization ellipse. Note that this does NOT change the local X axis of the source itself.
