Description

This command creates a new detailed source in the FRED document. In a detailed source the user has full control over the source attributes, including:

•Ray Positions/Directions

•Location/Orientation

•Power

•Coherence

•Polarization

•Wavelength

•Visualization

•Acceptance Filter

Navigation

This command can be accessed in the following ways:

•Menu > Create > New Detailed Source

•Ctrl + Alt + D

•Toolbar button:

•On the Optical Sources folder in the object tree view, right mouse click and select "Create New Detailed Optical Source"

Controls

The following table describes the controls available from the Source tab of a Detailed Source. Please see the related topics for help items regarding other Detailed Source dialog tabs.

Control	Input / Description	Defaults
Logical Parent	The logical parent of this source in the object tree view. Note that logical parent is different than the location parent.	Optical Sources
Name	The desired source name.	Source n
Description	A source description can be entered and will be displayed in the object tree view. Descriptions can be useful for keeping track of multiple source definitions.	Blank
Immersion Material
Name	Name of material in which rays are immersed when defined.	Air
Catalog	Specifies the catalog containing the immersion material currently in use. The Current catalog specifies the Materials folder of the object tree view.	Current
Select	Opens a dialog allowing selection of a catalog and material for immersion.
Additional Phase to Add to the Source
Phase	Add phase (in waves) to the rays prior to tracing . This allows definition of a phase relation between multiple sources.	0
Post-Creation Ray Propagation Specification
No Extra Propagation (do nothing)	This selection is made if no propagation is required.	Selected
Propagate by	Rays are propagated along their trajectory by the given distance in the specified direction. If the Ray trajectory is perpendicular to the propagation direction selected then the ray is not propagated.	Not Selected
Propagate to	Rays are propagated along their trajectory to their closest approach to the specified location. If the Ray trajectory is perpendicular to the propagation direction selected then the ray is not propagated.	Not Selected
Propagate to optical path length	Rays are propagated along their trajectory by the specified optical path length. Optical path length is equal to the physical distance divided by the index of refraction; OPL = d/n.	Not Selected
Propagate to Point	The rays are propagated along their trajectory to their closest approach to the specified point.	Not Selected
Propagate to sphere	The rays are propagated along their trajectory to their closest approach to the surface of the specified sphere. Select negative or positive direction.	Not Selected

OK	Accept settings and close the dialog box.
Cancel	Discard settings and close the dialog box.
Apply	Apply settings and keep dialog box open.
Help	Access this Help page.

Application Notes

Post creation ray propagation specification

The post creation ray propagation specifications ignore any surfaces between the ray creation position and the pre-propagation position. When the raytrace is initiated, the rays will then intersect any of the intermediate surfaces.
