Interference Pattern
The Interference Pattern () plot shows the intensity on a cut plane resulting from the interference of multiple rays passing through the cut plane. It is available with a 2D Plot Group, and you select it from the More Plots submenu. A Cut Plane data set pointing to a Ray (Data Set) data set must be used. The data set must point to an instance of the Geometrical Optics interface in which the ray intensity and phase are computed.
Go to Common Results Node Settings for links to information about these sections: Data, Title, Range, Coloring and Style, and Inherit Style. For Interference Patterns plots, only Cut Plane data sets are allowed as inputs.
The Interference Pattern plot is available with the Ray Optics Module.
Coordinate Range
Specify the origin of the coordinate system in which the interference pattern is plotted. From the Origin location specification list, select Manual (the default), By ray index, or At ray of greatest intensity. If Manual is selected, enter the Origin location, x component; Origin location, y component; and Origin location, z component. If the specified point does not coincide with the cut plane, the closest point on the cut plane is used as the origin. If By ray index is selected, enter the Ray index. The origin is then defined at the point where the ray of specified index intersects the cut plane. If At ray of greatest intensity is selected, the origin is located where the ray of greatest intensity intersects the cut plane. Select the Manual x range and Manual y range check boxes to adjust the size of the region in which the interference fringes are plotted. Enter a Resolution to determine the number of grid points in each direction that are used to render the interference pattern. The Resolution must be an integer from 0 to 1000.
