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 dataset pointing to a
Ray (Dataset) dataset must be used. The dataset must point to an instance of the Geometrical Optics interface in which the ray intensity and phase are computed.
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.
