Description When the Secondary diffraction efficiency specification of a grating surface is the Volume Hologram Efficiency type, this subroutine retrieves the algorithm mode specification as a string.
Syntax algo = GetDiffractEfficiencyVolHOEAlgorithmSecondary ( snode )
Parameters algo As String Returned string indicating the efficiency algorithm mode currently used by the Volume Hologram Efficiency specification. Possible return values are: "surface-based grating equation signal direction algorithm" “K-sphere (standard) signal direction algorithm” “K-closed (legacy) signal direction algorithm”
snode As Long This argument specifies the node number of the grating surface whose Secondary Volume Hologram Efficiency algorithm mode specification is being retrieved.
Example The example below demonstrates how to retrieve and report the Secondary diffraction efficiency specification of a Volume Hologram Efficiency type. Sub Main
Dim sNode As Long, algo As String sNode = FindFullName( "Geometry.Plane.Surface" )
algo = GetDiffractEfficiencyVolHOEAlgorithmSecondary( sNode ) Print "Algorithm = " & algo
End Sub
